Question

Me ajudem com esses cálculos : 3/5 + 2/7 +1/3

Answer 1

Boa Tarde,

$\frac{3}{5} + \frac{2}{7} + \frac{1}{3}$

MMC = 105

$\frac{63 + 30 + 35 }{105} = \frac{128}{105}$

Espero ter ajudado :)

Answer 2

= 3/5 + 2/7 +1/3
= (21.3 + 15.2 + 35.1)/105
= (63 + 30 + 35)/105
= (63 + 65)/105
= 128/105

5,7,3: 3
5,7,1: 5
1,7,1: 7
1,1,1 = 3.5.7 = 15.7 = 105

R.: 128/105
