you have 12 mp3 songs on your computer.1/4 of them don't work.How many mp3 do you have to buy to replace the ones don't work?

Respuesta :

12 in total. 

You would have to replace 3.

Just divide 12 by 4.

I hope this helps! (:
You have 12 mp3 songs and 1/4 don't work. So do 12*1/4 which is 3. So 3 songs aren't working, so replace them by buying 3 songs.
