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 :)<span />
