Total number of cards that Yoko and Julie shared = 100%
If Yoko gave 126 cards to Julie, 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 Yoko gave to Julie
= 71% - 50%
= 21%
21% → 126
1% → 126 ÷ 21 = 6
Number of cards that Yoko had
= 71%
= 71 x 6
= 426
Answer(s): 426
