Finding the answer to "of" problems

Today we continued finding the answers to "of" problems.  They are percentage problems that have a whole number and a percentage.

They look like this:

25% of 15

85% of 49

10% of 90

Tomorrow we continue with problems that contain "what number" situations.

I'll post more about that later tomorrow.  We will do a short quiz on the percents and missing numbers on Friday followed by a level up opportunity to improve an grades that are less than a 3.
