Total number of buttons that Kimberly and Tiffany shared = 100%
If Kimberly gave 36 buttons to Tiffany, 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 Kimberly gave to Tiffany
= 68% - 50%
= 18%
18% → 36
1% → 36 ÷ 18 = 2
Number of buttons that Kimberly had
= 68%
= 68 x 2
= 136
Answer(s): 136
