Question

Calcule as multiplicações e divisões de fração em Z
(+2/3). (-1/5)=​

Answer 1

$z\frac{2}{3}\left(-\frac{1}{5}\right)$

$=-z\frac{2}{3}\cdot \frac{1}{5}$

$-\frac{2z}{15}$ > Impar.

>>>>>>>>>>>   $\mathrm{X\:intersepta}:\:\left(0,\:0\right),\:\mathrm{Y\:intersepta}:\:\left(0,\:0\right)$

$y=-\frac{2}{3}\cdot \frac{1}{5}z$

$z=-\frac{2}{3}\cdot \frac{1}{5}y$

$-\frac{15z}{2}$

$-\frac{2}{3}\cdot \frac{1}{5}z$

$y=-\frac{2}{15}z$

$m=-\frac{2}{15}$
