The problem we are working is: If John can paint half of a room in two-thirds of an hour, what part of the room can he paint in a full hour?

Use the table at the right. What part of the room will John paint in one hour?

0.75(3/4) part of the room

Step-by-step explanation:

0.75(3/4) part of the room

Step-by-step explanation:

if he takes 2/3 hours to paint 0.5 room

x=0.5*3/2

x= 1.5/2

x=0.75 part of the room

75/100= 15/20=3/4 part
