if peter has 60 basball cards in his collection how many baseball football and basketball cards does he have?

my answer was-20 baseball cards
10 football cards
10 basketball cards

Insufficient data to answer. However, you already state he "has 60 baseball cards." On the other hand, if 60 is the total number, the three categories do not add up to the total.

Proofread you post for typos before you post it.

To determine the number of football and basketball cards Peter has, we need more information. The question only provides the number of baseball cards in his collection, which is 60. Without additional information, we cannot accurately determine the number of football and basketball cards.

It's possible that Peter has an equal number of all three types of cards, in which case he would have 20 baseball cards, 20 football cards, and 20 basketball cards. However, this is just one of many possible scenarios.
