Total number of buttons that Betty and Esther shared = 100%
If Betty gave 140 buttons to Esther, 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 Betty gave to Esther
= 85% - 50%
= 35%
35% → 140
1% → 140 ÷ 35 = 4
Number of buttons that Esther had
= 15%
= 15 x 4
= 60
Answer(s): 60
