Answer:

#-3/4#

Explanation:

This is all one term, but there are brackets which we need to simplify first. There are 2 terms inside the bracket.

#2(color(blue)(1/10*2 1/4)color(red)(- 3/5))#

=#2(color(blue)(1/10xx9/4)color(red)(- 3/5))#

=#2(color(blue)(9/40 )color(red)(- 3/5))#

=#2xx((9-24)/40)#

=#2xx (-15)/40#

=#(-15/20)#

=#-3/4#
