What is 24% of 80?
15 is 30% of what number?
20 is what percent of 52?
explain the method you chose to find the answer of each one!

In math, IS represents =    OF represents multiply 

1.   So for the first problem is saying 24% * 80 24% is the same as .24 so .24*80=19.2

2. For this one the problem is saying 15=30%*x  So for this we need to find x. So we divide both sides by .3 and get x = 50 

3. You do the same thing as in 2. Im not gonna do all ur homework so you can do this one.

Hope that helps :)
