Answer 1

The number of songs Kim started with are 18songs while the number of songs Eric started with are 36 songs.

Calculation of total songs owned by each trader

Firstly, Kim = 1/2 of Eric's

Ed = 1/3 of Kim= 6 songs

Eric = 2 songs

Total songs by the whole traders is = 12 ×3 = 36songs

• To find the total songs for Kim,

If Kim gave Ed, 1/3 of her songs =6 , then her whole song is 6×3 = 18songs.

But she gave out 6 to Ed so 12 songs will remain.

• To find total songs by Eric,

If 18 songs received by Kim is half of Eric songs therefore, 18×2 = 36

But half was given to Kim therefore 18 songs is remaining for Eric

• To find total songs by Ed,

Ed received 6songs from kim and gave out 2, there, 4 songs is remaining for Ed.

Therefore the number of songs Kim started with are 18songs while the number of songs Eric started with are 36 songs.
