Charlotte's family bought a 2- pound block of cheese. there is 1/4 of the block of cheese left. how many ounces of cheese has charlotte's family eaten ?

Charlotte's family ate 28 ounces of cheese because 1 pound equals 16 ounces plus 1 pound equals 16 ounces equals 32 ounces minus 1/4 pound equals to 4 ounces which equals to 28 ounces of cheese that Charlotte's family ate.

1 pound = 16 ounces
2 pounds = 32 ounces 

32÷4=8

8 ounces is 1/4 which is what was left. to find the 3/4 left, multiply 8 by 3 :

8×3=24 ounces

Charlotte's family ate 24 ounces or 1 pound 8 ounces

hope this helped
