Answer 2

Oie, Td Bom?!

A)

= 9/10 + 5/6

= 27/30 + 25/30

= [27 + 25]/30

= 52/30

= [52 ÷ 2]/[30 ÷ 2]

= 26/15

B)

= 7/8 + 2/3

= 21/24 + 16/24

= [21 + 16]/24

= 37/24

C)

= 3/2 + 5/6

= 9/6 + 5/6

= [9 + 5]/6

= 14/6

= [14 ÷ 2]/[6 ÷ 2]

= 7/3

D)

= 1/3 + 3/2 + 1/8

= 8/24 + 36/24 + 3/24

= [8 + 36 + 3]/24

= [44 + 3]/24

= 47/24

E)

= 7/6 + 1/5 + 1/8

= 140/120 + 24/120 + 15/120

= [140 + 24 + 15]/120

= [164 + 15]/120

= 179/120
