Answer:

#-4 9/10#

Explanation:

First, turn your proper fractions into improper fractions.

#-8 1/2 + 3 3/5#

#-17/2 + 18/5#

You need to create a common denominator so that you can add the numerators. Multiply the left by 5 and the right by 2.

#-85/10 + 36/10#

#(-85 + 36) / 10#

#-49/10#

Convert that back to a proper fraction.

#-4 9/10#
