Question

Four students were scheduled to give book reports in 1 hour. After the first report, 2/3 hour remained. The next two reports took 1/6 hour and 1/4 hour. What fraction of the hour remained

Answer 1

Answer:1/4 hour remaining

Explanation:

Presenter 1 - 1/3 hour

Presenter 2 - 1/6 hour

Presenter 3 - 1/4 hour

Convert to least common denominator of 12

4/12 + 2/12 + 3/12 = 9/12

12/12 - 9/12 = 3/12

Reduce 3/12 to get 1/4 hour remaining
