Total number of stamps that Lynn and Kathy shared = 100%
If Lynn gave 180 stamps to Kathy, both would have the same number of stamps.
Number of stamps that each would have in the end
= 100% ÷ 2
= 50%
Number of stamps that Lynn gave to Kathy
= 68% - 50%
= 18%
18% → 180
1% → 180 ÷ 18 = 10
Number of stamps that Lynn had
= 68%
= 68 x 10
= 680
Answer(s): 680
