Mark and Aly have left 35/9 or $3\frac{8}{9}$ pizza.

Step-by-step explanation:

Mark's pizza leftover = 2 1/3

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fraction:}\:a\frac{b}{c}=\frac{a\cdot \:c+b}{c}$

$2\frac{1}{3}=\frac{2\cdot 3+1}{3}=\frac{7}{3}$

Aly's pizza leftover = 1 5/9

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fraction:}\:a\frac{b}{c}=\frac{a\cdot \:c+b}{c}$

$1\frac{5}{9}=\frac{1\cdot 9+5}{9}=\frac{14}{9}$

The combined leftover pizza of Mark and Aly can be determined by adding the leftover of both pizza

i.e.

$\frac{7}{3}+\frac{14}{9}$

$=\frac{21}{9}+\frac{14}{9}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$

$=\frac{21+14}{9}$

$=\frac{35}{9}$ or $3\frac{8}{9}$

Thus, Mark and Aly have left 35/9 or $3\frac{8}{9}$ pizza.
