Questions and Solutions for NCERT Class 6th Mathematics Chapter 7 – Fractions – Exercise 7.4

1. Write shaded portion as fraction. Arrange them in ascending and descending order using correct sign ‘<’, ‘=’, ‘>’ between the fractions:

Solution:

(a) 3/8, 6/8, 4/8, 1/8

Ascending Order : 1/8 < 3/8 < 4/8 < 6/8

Descending Order : 6/8 > 4/8 > 3/8 > 1/8

(b) 7/9, 4/9, 3/9, 6/9

Ascending Order : 3/9 < 4/9 < 6/9 < 8/9

Descending Order : 8/9 > 6/9 > 4/9 > 3/9 

(c) Show 2/6, 4/6, 8/6 and 6/6 on the number line. Put appropriate signs between the fractions given.

Answer:

5/6 > 2/6 

3/6 > 0

1/6 < 6/6 

8/6 > 5/6

2. Compare the fractions and put an appropriate sign.

Answer:

(a) 3/6 < 5/6

(b) 1/7 < 1/4

(c) 4/5 < 5/5

(d) 3/5 > 3/7

3. Make five more such pairs and put appropriate signs.

Sol: (a) 5/7 > 2/7

(b) 9/10 < 10/10

(c) 4/15 > 2/15

(d) 7/11 < 8/11

(e) 2/3 < 1/3

4. Look at the figures and write ‘<’ or ‘>’, ‘=’ between the given pairs of fractions.

Solution:

(a) 1/6 < 1/3

(b) 3/4 > 2/6

(c) 2/3 > 2/4

(d) 6/6 = 3/3

(e) 5/6 < 5/5

5. How quickly can you do this? Fill appropriate sign. ( ‘<’, ‘=’, ‘>’)

Solution: 

(a) 1/2 > 1/5

(b) 2/4 = 3/6

(c) 3/5 < 2/3

(d) 3/4 > 2/8

(e) 3/5 < 6/5 

(f) 7/9 > 3/9

(g) 1/4 = 2/8

(h) 6/10 < 4/5

(i) 3/4 < 7/8

(j) 6/10 < 4/5

(k) 5/7 = 15/21

6. The following fractions represent just three different numbers. Separate them into three groups of equivalent fractions, by changing each one to its simplest form.

(a) 2/12   (b) 3/15   (c) 8/50    (d) 16/100   (e) 10/60   (f ) 15/75   (g) 12/60   (h) 16/96   (i) 12/75   (j) 12/72     (k) 3/18   (l) 4/25

Solution:

7. Find answers to the following. Write and indicate how you solved them.

(a) Is 5/9 equal to 4/5 ?

(b) Is 9/16 equal to 5/9 ?

(c) Is 4/5 equal to 16/20 ?

(d) Is 1/15 equal to 4/30 ?

Solution: 

8. Ila read 25 pages of a book containing 100 pages. Lalita read 2/5 of the same book. Who read less?

Solution: Total number of pages in the book = 100

Pages read by Ila = 25

Fraction of pages read by Ila = 25/100 = 1/4

Fraction of pages read by Lalita = 2/5

Since 1/4 < 2/5

Therefore, Ila read less.

9. Rafiq exercised for 3/6 of an hour, while Rohit exercised for 3/4 of an hour. Who exercised for a longer time?

Solution : Rafiq exercised for 3/6 of an hour

Rohit exercised for 3/4 of an hour 

Since 3/4 > 3/6

Therefore, Rohit exercised for longer time.

10. In a class A of 25 students, 20 passed in first class; in another class B of 30 students, 24 passed in first class. In which class was a greater fraction of students getting first class?

Solution: In class A, fraction of students passed in first class = 20/25 = 4/5

In class B, fraction of students passed in first class = 24/30 = 4/5

Hence, both class A and B has same fraction of students getting first class.
