Answer: [tex]2\frac{2}{19}[/tex] cases per hour.
Step-by-step 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 [tex]2\frac{3}{8}[/tex] 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:
[tex]2\frac{3}{8}=\frac{(2*8)+3}{8}=\frac{19}{8}[/tex]
Now you can write the following proportion:
[tex]\frac{5}{\frac{19}{8}}=\frac{x}{1}[/tex]
Solving for "x", you get:
[tex]x=\frac{40}{19}[/tex]
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:
[tex]x=2\frac{2}{19}[/tex]
