Question

como calcular e simplificar 2/7 + 1/10 + 3/2? e calcular o MMC ?

Answer 1

mmc é 70

(20+7+105)/70
132/70 simplificar por 2

61/35 ou 1,74...

Answer 2

= 2/7 + 1/10 + 3/2
= (10.2 + 7.1 + 35.3)/70
= (20+7+105)/70
= 132/70 (:2)/(:2)
= 66/35
----------------------------
MMC = 70
7,10,2: 2
7,5,1: 5
7,1,1:7
1,1,1 = 2.5.7 = 70

R.: 66/35
