What fraction of the carton of milk is left over?

Explain your solution using words,numbers,and or models?

Answer 1

1/12 of the milk is left.

Answer 2

Answer: The left fraction is 1/12

Step-by-step explanation:

We know that, of an initially full carton, the cats drink:

(1/3 + 5/12 + 1/6) = 2/6 + 1/6 + 5/12 = 3/6 + 5/12 = 6/12 + 5/12 = 11/12

So the cats drink 11/12 of the carton of milk, this mean that the milk left over in the carton is L = 1 - 11/12 = 12/12 - 11/12 = 1/12

So the fraction left milk in the box is 1/12
