Total number of buttons that Natalie and Jen shared = 100%
If Natalie gave 128 buttons to Jen, 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 Natalie gave to Jen
= 82% - 50%
= 32%
32% → 128
1% → 128 ÷ 32 = 4
Number of buttons that Natalie had
= 82%
= 82 x 4
= 328
Answer(s): 328
