Answer 1

He originally had on his MP 3 player 99 songs

Step-by-step explanation:

The given is:

• George deleted 63 songs from his MP 3 player
• The ratio of songs he deleted to the songs he kept was 7 : 4

We need to find how many songs he originally had on his MP 3 player

Let us solve this problem by using the ratio method

∵ George deleted 63 songs from his MP 3 player

∵ The ratio of songs he deleted to the songs he kept was 7 : 4

→  Deleted    :    Kept    :    total

→  7                :    4          :    11 (7 + 4 = 11)

→  63             :                 :    x

By using cross multiplication

∵ x × 7 = 63 (11)

∴ 7 x = 693

- Divide both sides by 7

∴ x = 99

∵ x represents the total number of songs

∴ He had 99 songs originally

He originally had on his MP 3 player 99 songs
