Last Friday, Jason purchased 12 packages of baseball cards. Each package contained 35 cards. If 1/7 of the cards featured pitchers, how many cards featured batters?
First, we need to find how many cards Jason purchased. 12 packages * 35 cards= 420 cards
if 1/7 of the cards are pitchers, then 6/7 feature batters.
360 cards featured batters.
