I can’t find the answer for this question

Answer 1

`x = (20)/(91)`

Explanation:

Since this is a proportion, first you need to cross multiply.

`(20)/(7)` ×
`(2)/(25)` =
`(40)/(175)`

`(26)/(25) x = (40)/(175)`

Now multiply both sides by the reciprocal of 26/25 which is 25/26.

`(25)/(26) ((26)/(25) )x=(40)/(175) ((25)/(26) )\\`

Cancel on the right side, 25 and 175, by 25. Then cancel 40 and 26 by 2.

`x = (20)/(7) ((1)/(13) )`

`x = (20)/(91)`
