Mo · Answer 1

Total number of songs in Julie's MP3 player = 860

Percentage of rap songs in Julie's MP3 player = 20%

Then

Number of rap songs in Julie's MP3 player = (20/100) * 860

= 860/5

= 172

Percentage of R&B songs in Julie's MP3 player = 15%

Then

Number of R&B songs in Julie's MP3 player = (15/100) * 860

= 1290/10

= 129

So

The number of other types of songs in Julie's MP3 player = 860 - (172 + 129)

= 860 - 301

= 559

So the number of other types of songs in Julie's MP3 player was 559.
