LESSON OVERVIEW
Recently, we have been dividing fractions by whole numbers, wholeby fractions, and we have been working on dividing fractions by frac
So far, weve been able to divide fractions by fractions with like denby dividing the two numerators.
Example: 48
2
8= 2, because they have the same denominatoran
Model:
Today we will work on dividing fractions by fractions withuncommon denominators.
