Answer 1

Step-by-step explanation:

a/b = 5/3

multiply 7 to denominators on both side

a/7b = 5/21 (7×3=21)

add 7b to numerator

a+7b/7b = 5+21/21

a+7b/7b = 26/21

Answer 2

The value of (a + 7b)/ 7b = 26/21.

Step-by-step explanation:

Given:-

(a/b) = 5/3

or, a = 5k, b = 3k

To find:-

Value of the ratio of (a + 7b)/ 7b = ?

Solution:-

Substitute:

[5k + 7(3k)]/[7(3k)]

=> (5k + 21k)/21k

=> 26k/21k

K will cancel out in both numerator and denomination.

=> 26/21

Hence, the value of (a + 7b)/ 7b = 26/21.
