Question

mAKE 1 equation with only numbers

Answer 1

Let's assume DeShawn had 18 cards and Stephanie had 18 cards, so their initial card collections were equal.

After selling half their card collections, DeShawn and Stephanie each have 18/2 = <<18/2=9>>9 cards left.

After buying 9 new cards, DeShawn has 9 + 9 = <<9+9=18>>18 cards.
After buying 9 new cards, Stephanie has 9 + 9 = <<9+9=18>>18 cards.

Thus, the ratio of the number of cards DeShawn has to the number Stephanie has is 18/18.

Simplifying the ratio, we get 1/1.
