Question

Jane watched one television program for 1/4 of an hour and then changed channels to watch another program for 20 min. Write an equation to describe the fraction of an hour that Jane watched television

Answer 1

Jane's TV watching = $\frac{1}{4}hours + 20mins$
=$\frac{1}{4}hours + (20mins)( \frac{1hour}{60mins})$
=$\frac{1}{4}hours + \frac{1}{3}hours$
=$\frac{3}{12}hours + \frac{4}{12}hours$
=$\frac{7}{12}hours$
