Question

Minnie spends 15.5 hours during a two week period to practice for a college entrance exam. At this rate how many hours will she spend during a 5 week period?

Answer 1

15.5 / 2 = 7.75.

7.75 * 5 = 38.75.

If you need to check:

7.75 + 7.75 = 15.5.

15.5 + 7.75 = 23.25.

23.25 + 7.75 = 31.0

31.0 + 7.75 = 38.75.

And there you have it!
