Question

A student solved this problem and said the answer is 1 3/4 quarts. Gary mixed 1/4 quart of plain milk and 2/3 quart of chocolate milk to make all the milk chocolate flavored. What was the total amount of chocolate flavored milk?
Is the student's answer reasonable?

Answer 1

Gary is wrong. the answer is 11/12.

1/4 + 2/3= n
1/4= 3/12
2/3= 8/12
3/12+8/12= 11/12 .
So, the answer cannot be 1 & 3/4.
