Answer 2

1)- 7/10 + 3/9  = 7/10 + 1.3/3.3 = 3x7+10x1/30 = 31/30 = 1  1/30

2)-. 7/8 + 5/12 = 3x7+2x5/ 24= 31/24 = 1  7/24

3)-. 5/6 + 3/20 =  10 x 5 + 3x 3/ 60 = 59/60

paso 1: ejercicio 4

1/4 + 4/5 + 3/2 = 5 x 1 + 4x 4/ 20 = 21/20 = 1  1/ 20

paso  2

1 1/20 + 3/2 = 21/20 + 3/2 = 21+10x3/20  = 51/20 = 2 11/ 20

ejercicio 5 :

15/ 7 + 7/5 + 1/3 =5 x 15 + 7x 7/35 = 124/35 = 3 19/ 35

paso 2:

3 19/ 35 + 1/3 = 124/35 + 1/3 = 3 x 124 + 35 x1 / 105 = 407/105 = 3  105/ 92
