Hannah played 4 songs in 2/3 hour how many songs did hannah play in 1h

Let r be the rate of Hannah can play songs each hour.

If she can play 4 songs in 2/3 hr

r = 4 songs / (2/3) hr = 12/2 = 6 songs/hour

For the total number of songs in a given amount of time, we use the equation

t (time in hours) * r (rate of song playing) = n (number of songs)

If t = 1 hr, r = 6 songs/hr, and t*r = n, n = 6

She played 6 songs in 1h
