NCERT Solutions for Class 6 Maths Chapter 7

NCERT solutions for class 6 Maths chapter 7

fraction class 6 represent parts of a whole or a collection of objects. This chapter introduces you to the basic concepts of fractions.

Key points:

Fraction: A number that represents a portion of a whole. It can be written in two parts: numerator (top number) and denominator (bottom number).
Types of Fractions:
- Proper Fraction: Numerator is smaller than the denominator (e.g., 1/4, 3/7).
- Improper Fraction: Numerator is greater than or equal to the denominator (e.g., 5/4, 7/7). Improper fractions can be converted to mixed numbers (whole numbers + fractions).
- Mixed Fraction: A combination of a whole number and a proper fraction (e.g., 1 ½, 2 ¾).
Representing Fractions: Fractions can be represented visually using fraction models (like circles or rectangles divided into parts), number lines, or fraction notation.
Comparing Fractions: We can compare fractions with the same denominator by looking at the numerators. The larger numerator represents the larger fraction.
Operations on Fractions:
- Addition and Subtraction: Requires fractions to have the same denominator. We add/subtract the numerators and keep the denominator the same.
- Multiplication: We multiply both the numerator and denominator of one fraction by the numerator and denominator of the other fraction.
- Division: We flip (reverse) the second fraction (divisor) and then multiply.

Additional concepts you might encounter:

Simplifying fractions: Reducing fractions to their lowest terms by dividing the numerator and denominator by the greatest common factor (GCD).
Equivalent fractions: Fractions that represent the same quantity even though they are written differently (e.g., 1/2 is equivalent to 2/4).

4. What fraction of a day is 8 hours?

Ans :

A day has 24 hours.

8 hours is a portion of the 24 hours.

Therefore, the fraction representing 8 hours is: 8/24.

5. What fraction of a hour is 40 minutes?

Ans :

An hour has 60 minutes.

40 minutes is a portion of the 60 minutes.

Therefore, the fraction representing 40 minutes is: 40/60.

6. Arya, Abhimanyu and Vivek shared lunch. Arya has brought two sandwiches, one made of vegetable and one of Jam. The other two boys forgot to bring their lunch. Arya agreed to share his sandwiches so that each person will have an equal share of each sandwich.

(a) How can Arya divide his sandwiches so that each person has an equal share?

(b) What part of a sandwich will each boy receive?

Ans :

Since there are 3 people sharing (Arya, Abhimanyu, and Vivek), Arya needs to divide each of his sandwiches (vegetable and jam) into 3 equal parts.

Since each sandwich is divided into 3 parts, each boy will get 1/3 of the vegetable sandwich and 1/3 of the jam sandwich.

7. Kanchan dyes dresses. She had to dye 30 dresses. She has so far finished 20 dresses. What fraction of dresses has she finished?

Ans :

Fraction of dresses finished = Number of dresses finished / Total number of dresses

Fraction of dresses finished = 20 dresses / 30 dresses

This simplifies to 2/3.

8. Write the natural numbers from 2 to 12. What fraction of them are prime numbers?

Ans :

List the natural numbers from 2 to 12: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
Identify the prime numbers:

A prime number has exactly two factors: 1 and itself. By checking each number’s divisibility:

Prime numbers: 2, 3, 5, 7, 11 (These numbers only have 1 and themselves as factors)

Calculate the fraction of prime numbers:

Total numbers = 11 (from 2 to 12)
Prime numbers = 5

There are 5 prime numbers out of 11 total numbers. We can express this as a fraction:

Fraction of prime numbers = Number of prime numbers / Total numbers

Fraction of prime numbers = 5 / 11

Therefore, 5/11 of the natural numbers from 2 to 12 are prime numbers.

9. Write the natural numbers from 102 to 113. What fraction of them are prime numbers?

Ans :

Analyze the numbers:

Most even numbers are not prime (divisible by 2).
We can quickly eliminate all even numbers (102, 104, 106, 108, 110, 112) from consideration of being prime.

Identify the remaining odd numbers:

This leaves us with odd numbers: 103, 105, 107, 109, 111, 113.

Check for primality in the remaining odd numbers:

105 is divisible by 3 (3 x 35).
111 is divisible by 3 (3 x 37).

Prime numbers:

Therefore, the prime numbers among 102 to 113 are: 103, 107, 109, 113.

Calculate the fraction:

Total numbers: 113 – 102 + 1 = 12 (from 102 to 113)
Prime numbers: 4 (103, 107, 109, 113)

Fraction of prime numbers = 4 / 12 = 1 / 3

Therefore, 1/3 of the natural numbers from 102 to 113 are prime numbers.

10 . What fraction of these circles have X’s in them?

Ans : Total circles = 8
Number of circles having X’s = 4
Required fraction = 4/8 = 1/2

11. Kristin received a CD player for her birthday. She bought 3 CDs and received 5 others as gifts. What fraction of her total CDs did she buy and what fraction did she receive as gifts?

Ans :

(a) Fraction of CDs bought:

Kristin bought 3 CDs.
We don’t know the total number of CDs yet, so let’s represent it as “x”.
The fraction representing the bought CDs is the number of CDs bought divided by the total number: 3 CDs / x.

(b) Fraction of CDs received as gifts:

Kristin received 5 CDs as gifts.
Again, using “x” for the total number of CDs, the fraction representing the gifted CDs is: 5 CDs / x.

(c) Total fraction of CDs:

To find the total fraction of CDs Kristin has (both bought and gifted), we need to add the fractions for bought and gifted CDs:

Total fraction = Fraction bought + Fraction received as gifts

Total fraction = (3 CDs / x) + (5 CDs / x)

Simplifying the expression (optional):

Since both fractions have the same denominator (x), we can simply add the numerators:

Total fraction = (3 + 5) CDs / x

Total fraction = 8 CDs / x

Therefore, Kristin has 8 CDs / x of her total CDs from buying and receiving gifts.

6. Check whether the given fractions are equivalent:

Ans :

a. 5/9 and 30/54

We have 5 x 54 = 270 and 9 x 30 = 270.

Since 5 x 54 = 9 x 30, it follows that

5/9 and 30/54 are equivalent fractions.

b. 3/10 and 12/50

We have 3 x 50 = 150 and 10 x 12 = 120.

Since 3 x 50 ≠ 10 x 12, it follows that

3/10 and 12/50 are not equivalent fractions.

c. 7/13 and 5/11

7. Reduce the following fractions to simplest form:

Ans :

Fraction in (a):

The text in image (a) is difficult to discern, but it appears to be 48/60.
- Reduce by finding the greatest common factor (GCD) of 48 and 60.
- GCD(48, 60) = 12 (both 48 and 60 can be divided by 12).
- Divide both numerator and denominator by 12: 48/60 = (48 / 12) / (60 / 12) = 4/5.

Therefore, the reduced form of the fraction in (a) is 4/5.

Fraction in (b):

The text in image (b) is also difficult to decipher, but it looks like 150/60.
- Reduce using the GCD: GCD(150, 60) = 30.
- Divide both numerator and denominator by 30: 150/60 = (150 / 30) / (60 / 30) = 5/2.

Therefore, the reduced form of the fraction in (b) is 5/2.

Fraction in (c):

The text in image (c) is unclear, but it seems to be 84/98.
- Reduce using the GCD: GCD(84, 98) = 14.
- Divide both numerator and denominator by 14: 84/98 = (84 / 14) / (98 / 14) = 6/7.

Therefore, the reduced form of the fraction in (c) is 6/7.

Fraction in (d):

The text in image (d) is difficult to make out, but it appears to be 12/52.
- Reduce using the GCD: GCD(12, 52) = 4.
- Divide both numerator and denominator by 4: 12/52 = (12 / 4) / (52 / 4) = 3/13.

Therefore, the reduced form of the fraction in (d) is 3/13.

Fraction in (e):

GCD(7, 28) = 7 (7 is a prime number and doesn’t share any factors with 28).
Reduced form: 7/28 is already in its simplest form (the numerator and denominator have no common factors).

Therefore, the reduced form of the fraction in (e) is 7/28 = 1/4

Ans :

Ramesh:
- Pencils used: 10
- Total pencils: 20
- Fraction used: Pencils used / Total pencils = 10 pencils / 28 pencils
  - Simplifying the fraction: We can’t simplify 10 and 28 further. Therefore, the fraction remains 1/2.
Sheelu:
- Pencils used: 25
- Total pencils: 50
- Fraction used: Pencils used / Total pencils = 25 pencils / 50 pencils
  - Simplifying the fraction: Dividing both numerator and denominator by 5 gives us 5/10. We can further simplify to 1/2.
Jamaal:
- Pencils used: 40
- Total pencils: 80
- Fraction used: Pencils used / Total pencils = 40 pencils / 80 pencils
  - Simplifying the fraction: Dividing both numerator and denominator by 40 gives us 1/2.

Yes, each has used up an equal fractions, i.e., 1/2

Exercise 7.5

1. Write these fractions appropriately as additions or subtractions.

Ans :

(a) 1/5 + 3/5 = 4/5 (shaded area is the sum of two colored sections)

2. Solve:

Ans :

3. Shubham painted 2/3 of the wall space in his room. His sister Madhavi helped and painted 1/3 of the wall space. How much did they paint together?

Ans :

They painted together ⅔ + ⅓ of the wall space.

To find the total area they painted, we can add the fractions:

⅔ + ⅓ = (2 x 1) / (3 x 1) + (1 x 1) / (3 x 1) = 2/3 + 1/3

Since they have the same denominator (3), we simply add the numerators:

2/3 + 1/3 = 3/3

However, 3/3 represents the entire wall space. Since painting the entire wall once is enough, we can simplify the answer:

3/3 = 1

Therefore, Shubham and Madhavi painted 1 (or the whole) wall space together.

4. Fill in the missing fractions.

Ans :

(a) 7/10 – □ = 3/10

We can start with the whole: 1 (representing the whole)
Subtract the fraction on the right: 1 – 3/10 = 7/10
This remaining fraction (7/10) is what needs to be divided into two parts.
So, the missing fraction on the left is the difference: 7/10 – □ = 3/10.
Therefore, the missing fraction in (a) is 4/10.

(b) □ – 3/21 = 5/21

Similar to (a), we can reason starting with the whole: 1.
Subtract the fraction on the right: 1 – 3/21 = 18/21
The missing fraction needs to be subtracted to result in 5/21.
So, the missing fraction in (b) is 18/21 – 3/21 = 15/21.

(c) □ – 3/6 = 3/6

In this case, both fractions have the same denominator (6).
We want to find a number that, when we subtract 3/6 from it, leaves 3/6 remaining.
The answer is simply 6/6 (the whole).
Subtracting 3/6 from 6/6 gives us 3/6 as expected.

(d) □ + 5/27 = 12/27

Here, we need to find a number that, when added to 5/27, gives us 12/27.
The missing fraction is 7/27.
Adding 5/27 and 7/27 gives us 12/27.

5. Javed was given 5/7 of a basket of oranges. What fraction of oranges was left in the basket?

Fraction of basket of oranges = 5/7

The fraction of the basket as a whole is 1.

∴ The fraction of the basket of oranges left is:

1−5/7=7/7−5/7=2/7

Thus, the required fraction is 2/7

8. Asha and Samuel have bookshelves of the same size partly filled with books. Asha’s shelf is ⅚ th full and Samuel’s shelf is ⅖th full. Whose bookshelf is more full? By what fraction?

Ans :

Compare Fractions: We need to compare ⅚ (Asha’s) and ⅖ (Samuel’s)

Asha: ⅚ * (5/5) = 25/30

Samuel: ⅖ * (6/6) = 12/30

25/30 (Asha) > 12/30 (Samuel)

Difference = Asha – Samuel = 25/30 – 12/30 = 13/30

Asha’s bookshelf is more full by a fraction of 13/30.
