Kelly was helping a friend with cleaning her bedroom. Kelly spent two hours and cleaned 80% of the room. what fraction of the room did Kelly help clean?
How would I solve this - divide?
80% = 80/100 = 8/10 = 4/5
To solve this problem, you would first find the fraction of the room that Kelly cleaned. Since Kelly spent two hours and cleaned 80% of the room, you can represent this as a fraction as follows:
80% can be written as 80/100, which simplifies to 4/5.
Therefore, Kelly helped to clean 4/5 or four-fifths of the room.
