Total number of buttons that Barbara and Ivory shared = 100%
If Barbara gave 126 buttons to Ivory, both would have the same number of buttons.
Number of buttons that each would have in the end
= 100% ÷ 2
= 50%
Number of buttons that Barbara gave to Ivory
= 64% - 50%
= 14%
14% → 126
1% → 126 ÷ 14 = 9
Number of buttons that Ivory had
= 36%
= 36 x 9
= 324
Answer(s): 324
