Finding Fifteen

Tim had nine cards, each with a different number from 1 to 9 on it.
He put the cards into three piles so that the total in each pile was 15.
How could he have done this?

Can you find all the different ways Tim could have done this?

Can we use the digits more than once when finding a different solution?

Hi Tahmid K,
No, you can use the card only once.
Hint: all the piles do not need to have the same number of cards.

These flollowing combonations are the ones I found:

8 ~ 5 ~ 2

6 ~ 9 and …….

7 ~ 4 ~ 3 ~ 1
