Question: Joseph had 16 baseball cards. He gave 3/8 of the cards to his brother and 2 cards to his brother. What percentage of the cards is left to Joseph? Think carefully first, then make a decision:
Joseph gave 16 x 3 / 8 = 6 cards to his brother. He gave a total of 6 + 2 = 8 cards to his brother and friend. Joseph has 16 - 8 = 8 cards left. This is 8 / 16 x 100% = 50% of his cards. So the answer is 50.
