Answer 1

-So, We have the following equation...  $>See \;Below$

$-7 \frac{2}{3} + -5 \frac{1}{2} + 8 \frac{3}{4}$

-First, we need to add $-7\frac{2}{3}$ and, $-5\frac{1}{2}$.   $>See\;Below$

$-7 \frac{2}{3} + -5 \frac{1}{2} = 13.1$

-Next, add $13.1$ and $8\frac{3}{4}$.   $>See\;Below$

$13.1+8\frac{3}{4} =21.85$

-So, your final answer is $21.85$!

In fraction form it is $21\frac{17}{20}$.

Changed to a improper fraction it is $\frac{437}{20}$!
