Question

In 7/8 hours, Isabel reads 2/5 chapters. what is the unit rate in chapters per hour?

Answer 1

Answer:

The unit rate in chapters 16/35 chapters per hour.

Step-by-step explanation:

The way I would solve this problem would be to set up a proportion. In this case, the proportion will be:

2/5 = x                   (or 2/5/7/8 = x/8/8) (8/8 stands for 1 hour)

7/8    8/8

After this we would mutliply the opposite sides. We multiply 2/5 by 8/8, where would get 16/40. On the other hand, when we multiply 7/8 by x, we get 7/8x.

After this, we need to isolate x to get our rate, so we would divide 16/40 by 7/8, getting us 16/35 as our answer.
