In order to answer this question you should first set up a general equation
3/10 of X (the number we want) = 15
When you see of in a mathematical question it generally means to multiply so...
(3/10)X = 15
you should start by getting rid of the fraction. To do this we need to multiply both sides by 10.
3X = 150
Then we need to divide by 3 to isolate the number that we want or X
X = 50
