turn the problem into a mathmatical equation
is ..... =
of...... x
what percent....... y
3 = y x 15
3 = 15y
divide each side by 15 to isolate the y
y = .2
the question asks for "what percent", so turn the .2 into a percent by moving the decimal place 2 spaces to the right
y = 20%
Hope this helped you!

In math "is" means "=" and "of" means "x". So the question translates to 3=What percent x 15. We can substitute the words "What percent" for "y". The question now is 3=y x 15. The question can be further simplified by multiplying y x 15 to get 15y. The question is now 3=15y. Now we simply divide y by 15 to take 15 away from the right side and get y by itself. We need to balance the left side of the equation so we divide 3 by 15. It can simplify to the fraction y=1/5. The percentage answer is 20%.

3 divides by 15 = .20
.20 x 100 = 20 %
