Answer:
number of songs = 9 songs
Step-by-step explanation:
According to Marcus the the song are each 3 start fraction , 1 divided by 2 end fraction minutes long. This can be expressed mathematically as 3 1/2 minutes long.
The slide show is 31, start fraction , 1 divided by, 2 end fraction minutes. This can be expressed also as 31 1/2 minutes long. The slide show contains the entire song.
Recall each song is 3 1/2 minutes long . The whole number fraction can be converted to improper fraction as 7/2 minutes long.
The whole slides show can be converted to improper fractions as 63/2 minutes long.
The number of song in the slideshow can be solved when we divide the total time in the slideshow by the time of each song.
number of songs = 63/2 ÷ 7/2
number of songs = 63/2 × 2/7
number of songs = 63/7
number of songs = 9 songs
