Total number of cards that Esther and Irene shared = 100%
If Esther gave 273 cards to Irene, 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 Esther gave to Irene
= 89% - 50%
= 39%
39% → 273
1% → 273 ÷ 39 = 7
Number of cards that Esther had
= 89%
= 89 x 7
= 623
Answer(s): 623
