Question

Find the number if 3/5 of it is 30

Answer 1

The number is 50

Explanation:

Use x to represent the unknown number

x(3/5) = 30

3/5x = 30

Multiply both sides of the equation by 5/3

5/3 * (3/5x) = 30/1 * (5/3)

x = 150/3

x = 50

The number is 50

Hope this helps :)

Answer 2

50

Explanation:

`(3)/(5) = (30)/(a)`

cross multiply, so 3a= 30x5

simplifies to 3a= 150

a = 50
