Total number of buttons that Xandra and Fiona shared = 100%
If Xandra gave 70 buttons to Fiona, 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 Xandra gave to Fiona
= 64% - 50%
= 14%
14% → 70
1% → 70 ÷ 14 = 5
Number of buttons that Xandra had
= 64%
= 64 x 5
= 320
Answer(s): 320
