Answer 1

Answer:

9 songs will be played in the slideshow.

Step-by-step explanation:

Duration of each song = 3 1/2 or 3.5 minutes.

Duration of Slideshow = 31 1/2 or 31.5 minutes.

Number of songs that will be played in the slideshow = ?

If we divide the total duration of the slideshow by the duration of each song, we will get the total number of songs that will be played in the slideshow.

31.5÷3.5 = 9

or

31 1/2 ÷ 3 1/2

63/2 ÷ 7/2

or 63/2 × 2/7

2 is cancelled by cross multiplication

63/7 = 9
