Jason gave away a third of his collection if hockey cards. if he gave away 360 hockey cards how many does he have left?

1/3 of 1080 is 360.

1080-360=720 cards left.

This is how I would think it could work. As If Jason had given away 360 cards and was asked how much left, it would be possible to multiply 360 by 3 as of flipping 1/3 to 3/1. So 360*3 = 1080

So taking 1080-360 would give you the remaining cards Jason has left so the answer will result 720 remaining
