Answer:
Mr. Cowin spent 5/12 of an hour playing the review game.
Explanation:
Mr. Cowin gave his students 3/4 of an hour to study for the test. After 1/3 of an hour, he played a review game for the remaining time.To find out how much time Mr. Cowin spent playing the review game, we need to subtract the time allocated for studying from the total time.Total time = 3/4 hourTime spent studying = 1/3 hourTime spent playing the review game = Total time - Time spent studyingTime spent playing the review game = 3/4 hour - 1/3 hourTo subtract fractions, we need to have a common denominator. In this case, the common denominator is 12.Time spent playing the review game = (9/12) - (4/12) = 5/12 hourTherefore, Mr. Cowin spent 5/12 of an hour playing the review game.
