Answer:
2(2)/(19) cases per hour.

Explanation:

Let be "x" the number of cases Jerry hears per hour.

According to the information provided in the exercise, you know that he hears 5 cases every
2(3)/(8) hours.

Convert from mixed number to improper fraction. The procedure is:

- Multiply the whole number part by de the denominator of the fraction.

- Add the product to the numerator.

- The denominator does not change.

Then:


2(3)/(8)=((2*8)+3)/(8)=(19)/(8)

Now you can write the following proportion:


(5)/((19)/(8))=(x)/(1)

Solving for "x", you get:


x=(40)/(19)

Make the conversion to mixed number:

- Dividing the numerator 40 by the denominator 19 you get a quotient of 2 (This will be the whole number part)

- The remainder you get is 2 (This will be the numerator).

- The denominator does not change.

Then:


x=2(2)/(19)
