jason mixed 3/8 cup of sugar with 1 5/6 cups of water. how many more cups of water than sugar did he use in his mixture?

You can find the answer by subtracting the amount of water he used by the amount of sugar he used. (1 5/6 - 3/8 = 1 11/24) To subtract mixed fractions, find a lowest common denominator by multiplying both of the denominators with different numbers until both denominators are the same. Then simply subtract. For example, multiplying 6 by 4 and 8 by 3 both get 24, so you can multiply the numerators by the same integers (5 by 4 and 3 by 3) to get the numerators on an equal fraction.
