Jack, jill and bill each carried a 48-ounce bucket full of water down the hill. by the time they reached the bottom, jack's bucket was only 3/4 full, jill's was 2/3 full, and bill's was 1/6 full. how much water did they spill altogether on their way down the hill?

Divide 48 by 4 and you get 12 ounces. Therefore, each 1/4 of a bucket  is equal to 12 ounces. divide 48 by 3 and you get 16 ounces. Therefore, each 1/3 of a bucket is 16 ounces. Divide 48 by 6 and you get 8 ounces. 8 multiplyed by 5 is 40. Add 40 16 and 12 and you get 68 ounces
