### Fractions Class 6 Ex 7.3

Ex 7.3 Class 6 Maths Question 1.
Write the fractions. Are all these fractions equivalent?

Solution:

Since all the fractions in their simplest form are not equal.
∴ They are not equivalent fractions.

Ex 7.3 Class 6 Maths Question 2.

Solution:

Ex 7.3 Class 6 Maths Question 4.
Find the equivalent fraction of 35 having
(a) denominator 20
(b) numerator 9
(c) denominator 30
(d) numerator 27
Solution:
(a) Here, we require denominator 20.
Let N be the numerator of the fractions.

∴ The required fraction is 1220

(b) Here, we required numerator 9.
Let D be the denominator of the fraction.

∴ The required fraction is 915.

(c) Here, we required denominator 30.
Let N be the numerator of the fraction.

∴ The required fraction is 1830.

(d) Here, we required numerator 27.
Let D be the denominator of the fraction.

∴ The required fraction is 2745.

Ex 7.3 Class 6 Maths Question 5.
Find the equivalent fraction of 3648 with
(a) numerator 9
(b) denominator 4
Solution:
(a) Given that numerator = 9

So, the equivalent fraction is 912.

(b) Given that denominator = 4
∴ N4 = 3648 ⇒ N x 48 = 4 x 36
⇒ N = 4×3648 = 3
So, the equivalent fraction is 34 .

Ex 7.3 Class 6 Maths Question 6.
Check whether the given fractions are equivalent:

Solution:
(a) 59 and 3054
We have 5 x 54 = 270
and 9 x 30 = 270
Here 5 x 54 = 9 x 30
∴ 59 and 3054 are equivalent fractions.

(b) 310 and 1250
We have 3 x 50 = 150
and 10 x 12 = 120
Here 3 x 50 ≠ 10 x 12
∴ 310 and 1250 are not equivalent fractions.

(c) 713 and 511
We have 7 x 11 = 77 and 5 x 13 = 65
Here 7 x 11 ≠ 5 x 13
∴ 713 and 511 are not equivalent fractions.

Ex 7.4 Class 6 Maths Question 1.
Write shaded portion as fraction. Arrange them in ascending and descending order using correct sign ‘<‘, ‘=’, ‘>’ between the fractions.

(c) Show 24 , 46 , 86 and 66 on the number line. Put appropriate signs between the fractions given.

Solution:
(a) Total number of divisions = 8
(i) Number of shaded parts = 3
∴ Fraction = 38

(ii) Total number of divisions = 8
Number of shaded parts = 6
∴ Fraction = 68

(iii) Total number of divisions = 8
Number of shaded parts = 4
∴ Fraction = 48

Number of shaded part = 1
∴ Fraction = 18
Now the fractions are:
38, 68, 48 and 18 with same denominator.

(b)(i) Total number of divisions = 9
Number of shaded parts = 8
∴ Fraction = 89
(ii) Total number of divisions = 9
Number of shaded parts = 4
∴ Fraction = 49
(iii) Total number of divisions = 9
Number of shaded parts = 3
∴ Fraction = 39
(iv) Total number of divisions = 9
Number of shaded parts = 6
∴ Fraction = 69
∴ Fractions are 89, 49, 39, 69 with same denominator.

Ex 7.4 Class 6 Maths Question 7.
Find answers to the following. Write and indicate how you solved them.

Solution:

By cross-multiplying, we get
5 x 5 = 25 and 4 x 9 = 36
Since 25 ≠ 36

By cross-multiplying, we get
9 x 9 = 81 and 16 x 5 =80
Since 81 ≠ 80

By cross-multiplying, we get
4 x 20 = 80 and 5 x 16 = 80
Since 80 = 80

By cross-multiplying, we get
1 x 30 = 30 and 4 x 15 = 60

Ex 7.4 Class 6 Maths Question 8.
Ila read 25 pages of a book containing 100 pages.
Solution:
Ila reads 25 pages out of 100 pages.

Lalita reads 25 of the same book.
Comparing 14 and 25 , we get
1 x 5 = 5 and 2 x 4 = 8
Since 5 < 8
∴ 14 < 25

Ex 7.4 Class 6 Maths Question 9.
Rafiq exercised for 36 of an hour, while Rohit exercised for 34 of an hour. Who exercised for a longer time?
Solution:
Rafiq exercised for 36 of an hour.
Rohit exercised for 34 of an hour.
Comparing 36 and 34 , we get
3 x 4 = 12 and 3 x 6 = 18
Since 12 < 18
∴ 34 > 36
Hence Rohit exercised for longer time.

Ex 7.4 Class 6 Maths Question 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, 20 students passed in first class out of 25 students.
∴ Fraction of students getting first class

In class B, 24 students passed in first class out of 30 students.
∴ Fraction of students getting first class

Comparing the two fractions, we get 45 = 45
Hence, both the class A and B have the same fractions.

A piece of wire 78 metre long broke into two pieces. One piece was 14 metre long. How long is the other piece?
Solution:
Total length of the wire = 78 metre
Length of one piece of wire = 14 metre
∴ Length of the other piece = 78 – 14
LCM of 8 and 4 = 8

Hence, the length of the other piece = 58 metre.

Ex 7.6 Class 6 Maths Question 7.
Nandini’s house is 910 km from her school. She walked some distance and then took a bus for 12km to reach the school. How far did she walk?
Solution:
Total distance from house to school = 910 km.
Distance travelled by Nandini by bus = 12 km
∴ Distance travelled by her on foot

Hence, the distance travelled by her on foot = 25km.

Ex 7.6 Class 6 Maths Question 8.
Asha and Samuel have bookshelves of the same size partly filled with books. Asha’s shelf is 56 th full and Samuel’s shelf is 25 th full. Whose bookshelf is more full? By what fraction?
Solution:
Asha’s shelf is 56 th full
and Samuel’s shelf is 25 th full
Comparing 56 and 25
LCM of 6 and 5 = 30

Hence, Asha’s shelf is full more than Samuel’s shelf.

Hence, 1330 th fraction is more full of Asha’s shelf.

Ex 7.6 Class 6 Maths Question 9.
Jaidev takes 215 minutes to walk across the school ground. Rahul takes 74 minutes to do the same. Who takes less time and by what fraction?
Solution:
Jaidev takes 215 minutes 5
Rahul takes 274 minutes
Comparing 215 minutes and 74 minutes

So, the time take to cover the same distance by Rahul is less than that of Jaidev.

Hence, Rahul takes 920 minutes less to across the school ground.
