Question

How can I solve 20% of 15?
Please help and please explain. I need this now!

Answer 1

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

Answer 2

To solve this, you can use this helpful equation:

$\frac{is}{of}$ = $\frac{percent}{100}$

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

$\frac{x}{15}$ = $\frac{20%}{100}$

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
