Total number of stickers that Winnie and Kathy shared = 100%
If Winnie gave 90 stickers to Kathy, both would have the same number of stickers.
Number of stickers that each would have in the end
= 100% ÷ 2
= 50%
Number of stickers that Winnie gave to Kathy
= 65% - 50%
= 15%
15% → 90
1% → 90 ÷ 15 = 6
Number of stickers that Winnie had
= 65%
= 65 x 6
= 390
Answer(s): 390
