Question

if a/b = 10/6 then find the ratio a+7b/7b=.

Answer 1

Answer:

a+7b/7b = 26/21

Step-by-step explanation:

given a/b = 10/6

can be solve as

a/b = 5/3

let us assume that

a = 5x  and b= 3x

now

a+7b = 5x + 7(3x)

a+7b = 5x + 21x = 26x

a+7b = 26x

now

7b = 7(3x)

7b = 21x

so we can write

a+7b/7b = 26x/21x

= 26/21

a+7b/7b = 26/21
