Explicación paso a paso:

En general voy a homogenizar las fracciones.

1) 3/8 + 1/4 + 1/2 = (3 + 2 + 4)/8 = 9/8

2) 5/4 + 3/2 + 5/3 = (15 + 18 + 20)/12 = 53/12

3) 4/5 + 1/2 - 1/10 = (8 + 5 - 1)/10 = 12/10 = 6/5

4) 2/7 - 5/2 + 5/14 = (4 - 35 + 5)/14 = -26/14 = -13/7

5) 2 - 3/4 + 1/5 = (40 - 15 + 4)/20 = 29/20

6) 1 2/3 + 2 1/5 -3 = (25 + 33 - 45)/15 = 13/15

7) 2 - 1 1/4 + 5/3 = (24 - 33 + 20)/12 = 11/12

8) 1 + 3/8 - 1 1/4 + 5/3 = (24 + 9 - 66 + 40)/24 = 7/24

9) 5 - 4 1/6 - 2/7 + 1 5/3 = (210 - 175 - 12 + 112)/42 = 135/42 = 45/14

10) 2 1/5 + 11/8 - 1 3/5 + 3 - 3/4 = (88 + 55 - 64 + 120 - 30)/40 = 169/40
