1.

Fine 30% of 70. The word of means multiply.

0.30 x 70 = 21

3. What percent of 56 is 14.

We don't know percent so we call it y. Remembering that of means multiply, we have y*56=14

solve for y. I get y = 14/56 = 0.25 as a decimal. You convert decimals to percents by multiplying by 100 (which is the same as moving the decimal to the right 2 places so 0.25 = 25%)

I think these two methods will solve most of the problems.

Check my work. I'm bad about typos.
