Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 2/3 of the area in 1/2 hour, how long will it take her to complete the entire picture?(1 point)
To find out how long it will take Charla to complete the entire picture, we need to find the time it took her to complete 1/3 of the area.
Since she completed 2/3 of the area in 1/2 hour, we can conclude that she completed 1/3 of the area in 1/2 hour as well.
Therefore, it will take her 1/2 hour to complete the entire picture.
To determine how long it will take Charla to complete the entire picture, we need to consider the amount of time it takes her to complete 2/3 of the area and calculate the remaining 1/3 of the area.
Given that she completes 2/3 of the area in 1/2 hour, we need to find the equivalent fraction for 1/3 of the area.
1/3 = (2/3) / 2
So, 1/3 of the area will take her 1/2 hour as well.
Therefore, it will take Charla a total time of 1/2 hour to complete the entire picture.
To solve this question, we need to understand the relationship between the time taken to complete a certain fraction of the area and the entire area.
We know that Charla completed 2/3 of the area in 1/2 hour. We need to find out how long it will take her to complete the remaining 1/3 of the area.
Since 1/2 hour is needed to complete 2/3 of the area, we can find the time needed to complete 1/3 of the area by dividing 1/2 hour by 2/3:
(1/2) hour ÷ (2/3) = (1/2) × (3/2) = (1 × 3)/(2 × 2) = 3/4 hour
Therefore, it will take Charla an additional 3/4 hour to complete the remaining 1/3 of the area.
