Answer
$\frac{22}{25}$
Work Step by Step
When $x=-\frac{1}{3}$, $y=\frac{2}{5}$, and $z=\frac{5}{6}$:
$\frac{y+x}{z}$
$=\frac{(\frac{2}{5})+(\frac{1}{3})}{(\frac{5}{6})}$
$=(\frac{2}{5}+\frac{1}{3})\div(\frac{5}{6})$
$=(\frac{6}{15}+\frac{5}{15})\div\frac{5}{6}$
$=\frac{11}{15}\div\frac{5}{6}$
$=\frac{11}{15}\times\frac{6}{5}$
$=\frac{11}{5}\times\frac{2}{5}$
$=\frac{22}{25}$
