Trey keeps sports cards in 3 drawers. Each drawer contains exactly 120 cards. In each drawer 2/3, of the cards are baseball cards, and 1/3 of the cards are a mixture of football, hockey, baseball, and soccer cards. If Trey decides to trade 1/4 of his baseball cards how many cards will he trade?

120 cards per drawer and 2/3 are baseball.
He has 240/3 = 80 baseball cards per drawer.
He actually has 240 baseball cards right? because he has 3 drawers.
He will trade 1/4 of the 240 = Can you finish it? 
no, i don't understand. please help me
