13. Ansel spent 2 hours working on a birdhouse. At the end of the 2 hours, he had finished ½ of the birdhouse. If he is able to finish the same fraction of a birdhouse every 2 hours, what fraction shows the number of birdhouses Ansel can make in 8 hours?

Ansel can finish the other half of the birdhouse in another 2 hours, for a total of 4 hours to complete one birdhouse.

In 8 hours, he can complete 8 ÷ 4 = 2 full birdhouses.

Therefore, the fraction that shows the number of birdhouses Ansel can make in 8 hours is 2/1 or simply 2.

To find the fraction of birdhouses Ansel can make in 8 hours, we need to determine how many sets of 2 hours are in 8 hours.

Since Ansel can make ½ of a birdhouse in 2 hours, he can make ½ x 4 = 2 birdhouses in 8 hours.

Therefore, the fraction that represents the number of birdhouses Ansel can make in 8 hours is 2/1.
