First, subtract the amount left from the beginning amount to find the amount eaten. So, 2 - 1/4 = 1 3/4 or 1.75.
There are 16 ounces in 1 pound, so we know the family ate at least 16 ounces. Because the family also at 3/4 of another pound, we divide 16 by 4 = 4. Next, subtract 4 from 16, so 16 - 4 = 12. Finally add 12 + 16 = 28.
Charlotte's family ate 28 ounces of cheese.
