Question

Ian creates a music playlist to listen to while doing chores. Playlist has 6 3/4 hours of music. He listens to 2/3 of playlist. How many hours did he spend cleaning

Answer 1

Answer:

$4\frac{1}{2}$ or 4.5 hours

Step-by-step explanation:

Total length of playlist = $6\frac{3}{4} = \dfrac{27}{4}$ hours

Time spent cleaning/listening = $\frac{2}{3}$ of total length of playlist

                                                  = $\dfrac{2}{3} \times \dfrac{27}{4} = \dfrac{9}{2}$ hours = $4\frac{1}{2}$ hours
