Total number of buttons that Roshel and Penelope shared = 100%
If Roshel gave 65 buttons to Penelope, 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 Roshel gave to Penelope
= 63% - 50%
= 13%
13% → 65
1% → 65 ÷ 13 = 5
Number of buttons that Roshel had
= 63%
= 63 x 5
= 315
Answer(s): 315
