Question

Sammy drinks 1/3 of the milk carton, Tikki drinks 5/12 of the milk carton, and Georgia drinks 1/6 of the milk carton. What fraction of the carton of milk is left over?

Answer 1

1/3 of the milk carton+ 5/12 of the milk carton+ 1/6 of the milk carton
= (4+5+2)/12 of the milk carton (common denominator).
= 11/12 of the milk carton.

Sammy, Tikki, and Georgia totally drink 11/12 of the milk carton.

1 milk carton- 11/12 of the milk carton
= 12/12 of the milk carton- 11/12 of the milk carton
= 1/12 of the milk carton.

There is 1/12 of the milk carton left over, so the final answer is 1/12 of the milk carton.

Hope this helps~ 

Answer 2

First we need to make all the fractions have the same denominator so our denominator is going to be 12 so 1/3=4/12
5/12 we are going to leave it untouched because it already has a denominator of 12 and 1/6=2/12 so
4/12+5/12+2/12=11/12
Now you are going to subtract 12/12-11/12 because 12/12 represents a whole so 12/12-11/12=1/12 so you have 1/12 of the milk left
