Answer:
1. Andrew grew 4 5/12 inches in 2 years
2. Abbey rode her bike for 3 3/8 hours in 2 days.
Step-by-step explanation:
When adding fractions you must have a common denominator for both of them.
First make the mixed fraction, improper fractions.
1 3/4 = 7/4
2 2/3 = 8/3
7/4 x 3/3 = 21/12
8/3 x 4/4 = 32/12
21 + 32 = 53
53/12 = 4 5/12
1 5/8 = 13/8
7/4 x 4/4 = 28/16
13/8 x 2/2 = 26/16
26 + 28 = 54
54/16 = 3 3/8
