Question

A -ounce serving of grapefruit juice contains  grams of water. How many grams of water are in  ounces of grapefruit juice?

Answer 1

The easiest way to do it would be to divide 159 grams by 6 ounces to see how many grams are in one ounce.

159/6=26.5

One ounce= 26.5 grams

26.5 grams times 8 ounces will give you the amount of grams of water there are in 8 ounces of grapefruit juice.

26.5 times 8= 212 Grams of water in 8 ounces of Grapefruit Juice

Answer 2

8 is 8/6 = 4/3 times 6

multiply 4/3 times 159 to get (4/3)(159) = 4(53) = 212 grams

8/6 = 212/159 = 4/3

212 = 159 + (1/3)159 = 159 + 53
