Question

Slove : 28/36 = 14/y

Answer 1

Explanation:

Apply proportions

y =(36*14)/28 = 18

Answer 2

y = 18

Explanation:

i) reduce the fraction with 4

`(28)/(36) = (14)/(y)`

`(28 / 4)/(36 / 4) = (14)/(y)`

`(7)/(9) = (14)/(y)`

ii) simplify the equation with cross multiplication

`(7)/(9) = (14)/(y)`

`7y = 14 * 9`

`7y = 126`

iii) divide both sides of the equation by 7

`(7y)/(7) = (126)/(7)`

`y = 18`
