Question

In 7/8 hours, Heather reads 2/5 chapters. What is the unit rate in chapters per hour? Write in simplest form

Answer 1

We have to find chapters/hour

So:

$\frac{\frac{2}{5}chapters}{\frac{7}{8}hours}\text{ = }\frac{2}{5}(\frac{8}{7})=\frac{16}{35}$

So, she reads 16/35 chapters in 1 hour.
