Total number of stamps that Lucy and Esther shared = 100%
If Lucy gave 198 stamps to Esther, 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 Lucy gave to Esther
= 72% - 50%
= 22%
22% → 198
1% → 198 ÷ 22 = 9
Number of stamps that Esther had
= 28%
= 28 x 9
= 252
Answer(s): 252
