Charltte's family bought a 2-pound block of cheese. There is 1/4 of the block of cheese left. How many onces of cheese has charlotte's family eaten?

Chaottes family ate 28 cheese

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.
