Answer 1

2/3+ 5/3= 7/3

8/10+ 3/9 = 102/90 simplificada 17/ 15

2/9 +3/9= 5/9

Answer 2

A). 2/3 + 5/3 = (2 + 5) / 3 = 7/3

B)  8/10 + 3/9 = [( 9×8) + (10×3)] /90 =[72+30]/90 = 102/90 = 51/45 = 17/15

C) 2/9 + 3/9 = (2 + 3)/9 = 5/9

D) 7/14 - 2/16 + 4/18 = 1/2 - 1/8 + 2/9 = [(1×36) + (1×9) + (8×2)] / 72 =

     [36+9+16]/72 = 61/72
