Total number of stickers that Winnie and Opal shared = 100%
If Winnie gave 60 stickers to Opal, 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 Opal
= 70% - 50%
= 20%
20% → 60
1% → 60 ÷ 20 = 3
Number of stickers that Opal had
= 30%
= 30 x 3
= 90
Answer(s): 90
