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.
