Peter had 12 baseballs cards he traded 1/2 of his cards with his cousin and 1/2 of his cards with tyrell how many cards did he keep

Respuesta :

None because 1/2 would be 6 and another would be 6 and add those together and they are 12
He didn't keep any because if he gave one half away he then had the other half left and then he gave the other half away he would be left with nothing.
