How to divide the fractions.

First, flip the second fraction over so it would be like this:

N/D x D/N

use this -> instead of / (dividing) because it confuses you and so you might flip the fraction over.

than do CROSS REDUCTION if possible and the rest of the steps are the same with multiplying fractions.

Boeun and Sarah's project is a slide show with bubbleshare.
