Total number of stamps that Gillian and Zoe shared = 100%
If Gillian gave 144 stamps to Zoe, 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 Gillian gave to Zoe
= 68% - 50%
= 18%
18% → 144
1% → 144 ÷ 18 = 8
Number of stamps that Gillian had
= 68%
= 68 x 8
= 544
Answer(s): 544
