a)

12 1/5 - 4 2/3 = 12 3/15 - 4 10/15 = 11 18/15 - 4 10/15 = 7 8/15

b)

2 4/5 + 3 2/5 = 5  6/5 = 6 1/5

c)

3 1/14 - 2 5/7 = 3 1/14 - 2 10/14 = 2 15/14 - 2 10/14 = 2/14

d)

3/5 - 1/2 + 3/4 = 12/20 - 10/20 + 15/20 = 2/20 + 15/20 = 17/20

e)

5 1/3 - 2  5/6  + 1/3 = 5 2/6  - 2 5/6 + 2/6 = 5 2/6 - 2 7/6 =

= 4  8/6 - 2 7/6 = 2 1/6
