Luke listens to the three most popular songs on the radio this week. The length of each song is shown. #1 song: 3 1/2 minutes #2 song: 2 57 /60 minutes #3 song: 4 3/4 minutes. What is the length of the three songs all together?

song 1: 3 1/2 minutes

song 2: 2 57 /60 minutes

song 3: 4 3/4 minutes

Total length of the three songs = song 1 + song 2 + song 3

= (3 1/2 + 2 57/60 + 4 3/4) minutes

= 7/2 + 177/60 + 19/4

= (210+177+285) / 60

= 672/60

= 56/5

= 11 1/5 minutes

Total length of the three songs = 11 1/5 minutes
