Type I (find the part/amount): What is 5% of 200?

Type II (find whole/base): 10 is 5% of what number?

Type III (find the %): 10 is what % of 200?

​

If you’re comfortable with solving algebraic equations, I recommend the translation method for all 3 types.

If you’re not, I recommend the translation method for type I and the proportion method for types II and III.

​

I don’t recommend Kaplan’s percent formula diagram method, as I find it unintuitive and hard to remember.

​

Type I is much more common than the others. I’d treat types II and III as optional.
