Danilo Salvatore - 19.01.2016 18:14There simply. First, let's find out how many songs from the total amount to hip-hop and pop: 25% - is 25 * 900/100 = 225 hip-hop songs 30% - is 30 * 900/100 = 270 Pop Songs Now count the number of other types of Songs: x + 225 + 270 = 900 x = 900-225-270 x = 405 The number of other types of Songs - 405

David_77 - 19.01.2016 18:25Hallo, Mark! Total number of songs in Ryan's player = 900 Percentage of hip-hop songs in Ryan's player = 25% Then Number of hip-hop songs in Ryan's player = (25/100) * 900 = 900/4 = 225 Similarly, you need to find the number of pop songs. After that you can find how many songs of other types are in the player. If you need more detailed help, you can ask me for a little fee
