1. For example, what is 1/20 of 80?

The word "of" is the same as the phrase "multiplied by."

We can rewrite "1/20 of 80" to "1/20 multiplied by 80."

(1/20)(80) = 80/20 = 4

Does that make sense?

3. Sure...

"5/20 of 80" can be rewritten as "5/20 multiplied by 80."

(5/20)(80) = 400/20 = 40 / 2 = 20

Got it?
