Answer

$-\frac{3}{4}$

Work Step by Step

Convert both of the numbers to improper fractions. $7\frac{3}{4}$ = $\frac{31}{4}$, $8\frac{1}{2}$ = $\frac{17}{2}$ Convert both of them to the same denominator. $\frac{17}{2}$ = $\frac{17\times2}{2\times2}$ = $\frac{34}{4}$ Adding a negative is the same as subtracting a positive. $\frac{31}{4} - \frac{34}{4}$ = $-\frac{3}{4}$
