Aaron has 120 sports cards. 3/8 of them are football cards and the rest are baseball cards. how many baseball cards does he have?

8/8 - 3/8 = 5/8

5/8 * 120 = 600/8 = 75 baseball cards

To find the number of baseball cards Aaron has, we first need to calculate the number of football cards he has.

We are given that 3/8 of the total number of cards are football cards. To determine how many football cards Aaron has, we can multiply the total number of cards by the fraction of football cards: 3/8 * 120 = 45.

We can now find the number of baseball cards by subtracting the number of football cards from the total: 120 - 45 = 75.

Therefore, Aaron has 75 baseball cards.
