Total number of buttons that Jade and Risa shared = 100%
If Jade gave 170 buttons to Risa, 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 Jade gave to Risa
= 67% - 50%
= 17%
17% → 170
1% → 170 ÷ 17 = 10
Number of buttons that Risa had
= 33%
= 33 x 10
= 330
Answer(s): 330
