Question

3/5 of a number is 30 what's the number?

Please answer, doing it for my little sis and don't remember it from my years :))

Answer 1

Hi! The answer will be 50. If you simplify 30/50, you can divide both by 10 to get 3/5.

Hope this helps!  :)

Answer 2

Answer: x= 50

Form your equation. The 'of' in the question means multiplication. 
3/5x = 30

Solve.
3/5x = 30          Divide by 3/5 to both sides 
x = 50               Answer!
