Terry wants to divide his 120 baseball cards into two groups, so that the ratio of the number of cards in the first group to the number of cards in the second group is 2 to 3. How many cards will be in each group?
Let the number of cards in each group be 2x and 3x. So, 2x + 3x = 120 5x = 120 x = 120 / 5 x = 24 Number of cards in each group is 2x = 2 × 24 = 48 3x = 3 × 24 = 72
