Total number of cards that Winnie and Gwen shared = 100%
If Winnie gave 66 cards to Gwen, both would have the same number of cards.
Number of cards that each would have in the end
= 100% ÷ 2
= 50%
Number of cards that Winnie gave to Gwen
= 72% - 50%
= 22%
22% → 66
1% → 66 ÷ 22 = 3
Number of cards that Winnie had
= 72%
= 72 x 3
= 216
Answer(s): 216
