translation tip
N is M of (what number) means
N = M * (what number)
so
fifteen is .30 of what number means
15 is .30 of (what number) means
15 = .30 * (what number)
what number = 15/.30 = 50
number = 50

You mean 30%.
30/100 = 15/x
1500 = 30x
x = 50

Let x = the number
Equation:
x * 0.3 = 15
x = 15 / 0.3
x = 50

To calculate that, you take 15 and multiply it by .30's inverse (3.33333333) which equals 50

ratio:
is/of
15/of = .3/1
cross multiply
15(1) = .3of
15 = .3of
divide both sides by .3
of = 50
15 is .3 of 50
