Ed has a water container that holds 3 gallons of water. Ed used water from a full container to fill four bottles that each hold 8 ounces and a pitcher that holds 1 quart. How many ounces of water are left in the water container?

Answer: = 324 ounces left over from 384 ounces

1 quart is 32 and 8 x 4 = 32 We add them together; 32 + 32 = 64 ounces then convert 3 gallons to ounces = 384

We subtract;

384-64=324 ounces.

We convert again 128 p/g + 128p/g = 256 ounces = 2 gallons

We subtract; 324-256 = 68

We divide;

364/68 = 91/17 = 5 + 6/17 = < 1/6

364/64 = 90/14 = 5 + 7/10 = < 1/6

64 = < 1/5 of 384 ounces

324 = < 384 ounces

2 gallons, plus 17/32 units of a gallon. = exact = 324 ounces.

as 68/128 = 128/68 = / 4 each = 17/32
