#-5 1/10#

Turn each into an improper fraction.

#2 2/5 = 12/5# and #-2 1/8 = -17/8#

#12/5 xx-17/8#

Then cross cancel to make it easier.

#cancel12^3/5 xx-17/cancel8^2#

#12 and 8 rarr 3 and 2#.

Then multiply straight across.

#3xx17= 51, and 5xx2= 10.#

# 51/10 = 5 1/10#

but then you have to take the negative sign into account, so the final answer would be #-5 1/10.#
