Answer:
13.8 gallons per hour
Step-by-step explanation:
"Gallons per hour" means to divide gallons by hours. Even the label can be a reminder of what to do: [tex]\frac{\text{gal}}{\text{hr}}[/tex] .
Now for the math...
[tex]4\frac{5}{16} \div 1.25 =4\frac{5}{16} \div 1\frac{1}{4}[/tex]
Changing both numbers to mixed number form helps. (You could also change both numbers to decimals--a calculator would help!)
Change mixed numbers to improper fractions, then divide.
[tex]\frac{69}{4} \div \frac{5}{4}=\\\\\frac{69}{4} \times \frac{4}{5}=\\\\\\\frac{69}{5}=13.8[/tex]
