Question

Jean mixed 3 1/3 qt of yellow paint and 2 1/3 qt of blue paint to make green paint.

How many quarts of green paint did Jean make?

Answer 1

3 1/3 when writen as mixed fraction = (3*3+1)/3= 10/3.
Similarly 2 1/3 = 7/3.
Adding both of them, we get
10/3 +7/3 = 17/3, which is nothing but
3) 17 (5
-15
2
Implies 5 2/3.
Thus 3 1/3+2 1/3= 5 2/3.
