Question
Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 23 of the area in 12 hour, how long will it take her to complete the entire picture?(1 point)
of an hour

Answer 1

To find how long it will take Charla to complete the entire picture, we can set up a proportion using the information given:

23 of the area completed in 12 hours
1 of the area completed in x hours

Cross multiplying, we get:

23 * x = 1 * 12
23x = 12
x = 12/23

Therefore, it will take Charla 12/23 of an hour to complete the entire picture.
