charla wants to cover a certain rectangular area of her drive way with a picture using chalk if she completes 2/3 of the area in 1/2 hour how long will it take to complete the entire picure?

Answer 1

If Charla completes 2/3 of the area in 1/2 hour, it means that 1/3 of the area is left to be completed.
To find out how long it will take to complete the whole picture, we need to determine the time it takes to complete 1/3 of the area.
Since 1/3 of the area takes 1/2 hour, then 1 whole area takes 1/2 hour x 3 = <<1/2*3=1.5>>1.5 hours.
Therefore, it will take Charla 1.5 hours to complete the entire picture. Answer: \boxed{1.5}.
