Question

(2/3)+(4/6)-(1/2)+3=

Qual o resultado ?

Answer 1

2/3 + 4/6 - 1/2 + 3
MMC = 6
2/3/2 + 4/6/1 - 1/2/3 + 3/1/6
4/6 + 4/6 - 3/6 + 18/6
8/6 - 3/6 + 18/6
5/6 + 18 /6 = 23/6

Answer 2

Solução:

$\frac{2}{3} + \frac{4}{6} -\frac{1}{2} +\frac{3}{1}$


MMC (3, 6, 2)

3, 6, 2 / 2
3, 3, 1 / 3
1, 1 / 6 ← MMC


$\frac{2}{3} + \frac{4}{6} -\frac{1}{2} +\frac{3}{1} = \frac{4+4-3+18}{6} = \frac{23}{6}$
