Question

Gianna Walsh · Accepted Answer

Answer: 79 ounces = 2 quarts and 15 ounces.
Explanation:
1) The question is:

1 gallon - (1 quart + 1 pint + 1 ounce)

2) To add and subtract those amounts you have to convert all to one same unit.
3) Since the least unit is ounce, I will convert gallon, quart and pint to ounces.
4) Conversion factors:
1 gallon = 4 quart
1 quart = 2 pints
1 pint = 16 ounces
5) Conversions:
i)

1 gallon \times 4 quart / gallon \times 2 pint / quart \times 16 ounce / pint = 128 ounces

ii)

1 quart \times 2 pint / quart \times 16 ounce / pint = 32 ounces

iii)

1 pint \times 16 ounce / pint = 16 ounces

4) Subtract:

1 gallon - (1 quart + 1 pint + 1 ounce) = 128 ounces - (32 ounces + 16 ounces + 1 ounce) = 128 ounces - 49 ounces = 79 ounces \leftarrow answer

You can convert it to a mixed number in this way:

79 ounces \times 1 quart / 32 ounces = 2. 46875 quarts

0.46875 quarts \times 32 ounces / quart = 15 ounces

Then,

79 ounces = 2 quarts and 15 ounces .
