1. 5 1/2 + 3 1/4 2. 6 4/5 + 9 9/10

1. 5 1/2 + 3 1/4 = 11/2 + 13/4 = 22/4 + 13/4 = 35/4 = 8 3/4

2. 6 4/5 + 9 9/10 = 34/5 + 99/10 = 68/10 + 99/10 = 167/10 = 16 7/10

1. 5 ½ + 3 ¼ = 11/2 + 13/4
n = 22/4 + 13/4
n = 35/4
n = 8 ¾

2. 6 ⁴/5 + 9 9/10 = 34/5 + 99/10
n = 68/10 + 99/10
n = 167/10
n = 16 7/10
