c, 5$\frac{1}{3}$ - (2$\frac{1}{5}$ + 4$\frac{1}{3}$)
$=$ 5$\frac{1}{3}$ - 2$\frac{1}{5}$ - 4$\frac{1}{3}$
$=$ (5$\frac{1}{3}$ - 4$\frac{1}{3}$) - 2$\frac{1}{5}$
$= 1 -$ $\frac{11}{5}$
$=$ $\frac{-6}{5}$
d, $\frac{-5}{11}$ . $\frac{4}{13}$ + $\frac{-5}{11}$ . $\frac{9}{13}$ + 3$\frac{5}{11}$
= $\frac{-5}{11}$ . ($\frac{4}{13}$ + $\frac{9}{13}$) + $\frac{38}{11}$
= $\frac{-5}{11}$ + $\frac{38}{11}$
= $\frac{33}{11}$ = $3$
