All of question 2 and 3

Hi. If you need me to explain please tell me so I will edit this comment. I'll just solve the answers for you... basically if they have a common denominator just add/ subtract, and if they don't, make it so they do by multiplying the same on each side.

2)
a. 1 3/4 + 2 1/4 = 4
b. 3 7/10 + 1 1/10 = 4 4/5
c. 2 1/8 + 3 3/8 = 5 1/2
d. 5 1/2 + 3 1/4 = 8 3/4
e. 5/8 + 2 1/4 = 2 7/8
f. 3 3/10 + 5 2/5 = 8 7/10

3)
a. 2 7/10 - 1 3/10 = 1 2/5
b. 3 5/8 - 2 3/8 = 1 1/4
c. 1 5/6 - 1/6 = 1 2/3
d. 3 7/10 - 1 1/2 = 2 1/5
e. 4 3/5 - 2 = 2 3/5
f. 1 3/8 - 1 1/8 = 1/4
