Question

From the following pairs of the number find the reduced form of ratio of first number to second number
1.72,60
2.38,57
3.52,78
​

Answer 1

Answer:

1. 6:5

2. 2:3

3. 2:3

Step-by-step explanation:

(i)

72 : 60 =

72

60

=

72÷12

60÷12

=

6

5

= 6 : 5 (HCF of 72 and 60 = 12)

Thus, the reduced form of 72 : 60 is 6 : 5.

(ii)

38 : 57 =

38

57

=

38÷19

57÷19

=

2

3

= 2 : 3 (HCF of 38 and 57 = 19)

Thus, the reduced form of 38 : 57 is 2 : 3.

(iii)

52 : 78 =

52

78

=

52÷26

78÷26

=

2

3

= 2 : 3 (HCF of 52 and 78 = 26)

Thus, the reduced form of 52 : 78 is 2 : 3.
