Gerry has 50 sports trading cards. Of those cards, 1/5 of them are baseball cards, 1/10 of them are football cards, and the rest are basketball cards. How many more basketball cards than baseball cards does Gerry have?

Answer: he has 15 more basketball cards than baseball cards.

Step-by-step explanation:

The total number of sport trading cards that Gerry has is 50.

Of those cards, 1/5 of them are baseball cards. This means that the number of baseball cards that he has is

1/5 * 50 = 10

1/10 of them are football cards. This means that the number of football cards that he has is

1/10 * 50 = 5

If the rest are basketball cards, it means that the number of basketball cards that he has is

50 - (10 + 15) = 50 - 25 = 25

Therefore, the number if basketball cards that he has more than baseball cards is

25 - 10 = 15
