G) 9/2 + 5/3​

Answer 1

Resposta:

Explicação passo-a-passo:

A) 5/7 + 3/7= 8/7

B) 8/5 + 7/5= 15/5 : 5 = 3/1

C) 7/2 + 5/2= 12/2 : 2 = 6/1

D) 8/3 + 5/3= 13/3

E) 3/4 + 5/2= 3/4 *2 = 6/8, 5/2*4= 20/8 = 6/8 + 20/8 = 26/8 : 2= 13/4

F) 3/5 + 7/6= 3/5*6 = 18/30, 7/6*5 = 35/30 = 18/30 + 35/30 = 53/30

G) 9/2 + 5/3= 9/2*3 = 27/6, 5/3*2 = 10/6 = 27/6 + 10/6 = 37/6

espero ter ajudado!!
