Total number of cards that Esther and Betty shared = 100%
If Esther gave 125 cards to Betty, 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 Betty
= 75% - 50%
= 25%
25% → 125
1% → 125 ÷ 25 = 5
Number of cards that Esther had
= 75%
= 75 x 5
= 375
Answer(s): 375
