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
