The russell family keeping track of the amount they drink each week. the first week they drank 2 gallons 1 quart in 1 cup of milk the second week they drank 3 gallons of milk many more cups of milk do they drink the second week than the first week

So first we convert to a common number(cups are the smallest so we'll convert to that)
2cups=1pint
2pints=1quart
4quarts=1gallon
1gallon=8pints
1gallon=16cups
1quart=4cups
first week they drank 2 gallons or 2 times 16 cups or 32 cups, 1 quart which is 4 and 1 cup so 32+4+1=37 cups the first week

week two 3 gallons which is 16 times 3 which is 48 cups in second week

second week-first week =difference
48-37=11

11 cups difference

What is the rest of the question?
