To find out how many ounces are in one gallon, we can observe the relationship between gallons and ounces from the table.
From the table:
- 5 gallons = 640 ounces
To find out how many ounces are in 1 gallon, we can divide the number of ounces by the number of gallons:
\[ \text{Ounces per gallon} = \frac{640 \text{ ounces}}{5 \text{ gallons}} = 128 \text{ ounces per gallon} \]
So, there are 128 ounces in one gallon.
