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
