Step-by-step explanation:

Change them into improper fractions. Multiply the denominator by the whole number and then add the numerator. Put that number over the denominator.

2 X 3 = 6 3 X 2 = 6

6 + 1 = 7 6 + 1 = 7

7/3 7/2

New expression: 7/3 + 7/2

Find a common denominator. Both denominators can go into 6.

14/6 + 21/6 = 35/6

Change this back into a mixed number by dividing.
