Total number of buttons that Nora and Kathy shared = 100%
If Nora gave 306 buttons to Kathy, 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 Nora gave to Kathy
= 84% - 50%
= 34%
34% → 306
1% → 306 ÷ 34 = 9
Number of buttons that Kathy had
= 16%
= 16 x 9
= 144
Answer(s): 144
