Given that:- time time spend= 105 minutes

reading=20 minutes

practicing the piano=30 minutes

cleaning the room=?

homework=40 minutes

so, total time spend= reading + practicing the piano + cleaning the room + homework

105=20+30+x+40

105=x+90

x=105-90

x=15 minutes  (cleaning the room)

friction for time taken to cleaning the room = 15/105

=3/21

=1/7

so, time taken to clean the room is one parts of time from 7 parts.
