I teach my students to remember "IS over OF equals % over 100"
Use x as the unknown value and then cross multiply and solve.
It works for every percent problem.
Here are the three different examples:
1. What is 30% of 40?
Set it up as x / 40 = 30 / 100
x = 12
2. 18 is 40% of what number?
18 / x = 40 / 100
x = 45
3. What percent is 30 out of 50?
30 / 50 = x / 100
x = 60
I like this method because the students don't have to worry about moving the decimal. I think it is a very easy way to teach them percentages, I hope this helps.

1) Try a calculator! It's ten times easier.
And....
2) Just remember. If you're given a number that's say .13, just move the decimal back twice. They percentage is 13%!
I hope this helps!
