7 gallons are equal to _________ ounces.

We convert from gallons to quarts by multiplying the number of gallons by 4 because:
1 gal = 4 qt
So we have :
7 gal × 4 qt/gal = 28 qt
We convert from quarts to pints by multiplying the number of quarts by 2 because:
1 qt = 2 pt
So we have :
28 qt × 2 pt/qt = 56 pt
We convert from pints to cups by multiplying the number of pints by 2 because:
1 pt = 2 cups
So we have :
56 pt × 2 cups/pt = 112 cups
We convert from cups to ounces by multiplying the number of cups by 8 because:
1 cup = 8 oz
So we have :
112 cups × 8 oz/cups = 896 oz
Therefore 7 gallons is equal to 896 ounces.
