Total number of buttons that Tina and Marion shared = 100%
If Tina gave 190 buttons to Marion, 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 Tina gave to Marion
= 69% - 50%
= 19%
19% → 190
1% → 190 ÷ 19 = 10
Number of buttons that Tina had
= 69%
= 69 x 10
= 690
Answer(s): 690
