15 times 20 over 100, or 1 fifth. 15 times 1 fifth is 3.

To solve this, you can use this helpful equation:


(is)/(of) =
(percent)/(100)

Since you now have this equation, you can just plug in.


(x)/(15) =
(20%)/(100)

To find x you would cross multiply, multiply the x with 100 and the 15 with the 20%.

100x = 300

Now to find x you would just divide both sides by 100.

x=3
