Question

the milk carton had 8/9 gallons in it before stu took a drink .if he drank 1/12 of a gallon how much milk is left

Answer 1

29/36

Explanation:

The milk carton has 8/9 gallons. When he drank 1/12 of a gallon, we have

8/9 - 1/12

Make the denominators of the 2 fractions the same :
8/9 = 8x4/9x4 = 32/36
1/12 = 1x3/12x3 = 3/36
So, the amount of milk left is : 32/36-3/36 = 29/36
