Frações ​

Answer 1

Resposta:

Explicação passo-a-passo:

A) 1/2+1/3+1/4= (mmc entre 2, 3 e 4 = 12)

(6+4+3)/12 = 13/12

B) 2/3+3/5+1/15= (mmc entre 3, 5 e 15 = 15)

(10+9+1)/15 = 20/15 = 4/3

C) 1/6+4/5+2/3= (mmc entre 3, 5 e 6 = 30)

(5+24+20)/30 = 49/30

D) 1/2+1/3+5/6= (mmc entre 2, 3 e 6 = 6)

(3+2+5)/6 = 10/6 = 5/3
