Question

A gallon jug of milk is 3/4 full. After breakfast the jug is 1/12 full. Find the difference of the amounts before breakfast and after breakfast.

Answer 1

Answer: So before the breakfast, we have 3/4 of the gallon jug of milk, and after we have 1/12 and want to know the difference between this quantities.

whe can write 3/4 as 9/12, and this way the subtraction is easy:

9/12 - 1/12 = 8/12= 2/3.

So in the breakfast you drinked 2/3 of the gallon

Answer 2

They drunk 2/3 because 3/4=9/12-8/12=1/12 and 8/12 is equal to 2/3 so 2/3 is your answer.
