Jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears cases at a constant rate. How many cases does he hear per hour?

You can use a ratio to solve this:

5 : 2 3/8

1 : ?

Determine the difference between 5 and 1.

1/5 = 0.2

Now multiply 2 3/8 by that same change.

2 3/8 x 0.2 = 0.475

5 : 2 3/8

1 : 0.475

Jerry listens to 0.475 cases an hour. I don't want to figure out the fraction for this, but I'm sure if you Google it you can find it.

1.4 cases per hour because 3/8 equals. 4
