Question

calcule e dê o resultado na forma de fraça

a) (-2/3)+(+1/2)​

Answer 1

Resposta:

a) (-2/3) + (+1/2)​ = -1/6

-2 + 1 = -1

2 . 3 = 6

Answer 2

3 , 2 | 2

3 , 1 | 3

1 , 1 MMC 2×3 = 6

$a)( - \frac{2}{3} )+ ( + \frac{1}{2} ) =$

$- \frac{2}{3} + \frac{1}{2} =$

$\frac{ - 4 + 3}{6} =$

$- \frac{1}{6} = - 0.16$
