Question

Me ajuda não sei essa

Answer 1

$\frac{ - 2}{3} + \frac{1}{1} - \frac{3}{2} . \frac{8}{9}$

$\frac{ - 2}{3} + \frac{1}{1} - \frac{24}{18}$

MMC de 3,1,18| 2

3,1,9| 3

1,1, 3| 3

1,1, 1 | 2×3×3= 18

$\frac{ - 12}{18} + \frac{18}{18} - \frac{24}{18}$

$\frac{6}{18} - \frac{24}{18} = \frac{ - 18}{18} = - 1$
