Total number of buttons that Diana and Tina shared = 100%
If Diana gave 138 buttons to Tina, 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 Diana gave to Tina
= 73% - 50%
= 23%
23% → 138
1% → 138 ÷ 23 = 6
Number of buttons that Tina had
= 27%
= 27 x 6
= 162
Answer(s): 162
