    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:  \frac{\text{gal}}{\text{hr}} .

    Now for the math…

    4\frac{5}{16} \div 1.25 =4\frac{5}{16} \div 1\frac{1}{4}

    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.

    \frac{69}{4} \div \frac{5}{4}=\\\\\frac{69}{4} \times \frac{4}{5}=\\\\\\\frac{69}{5}=13.8
