Total number of pens that Jade and Kylie shared = 100%
If Jade gave 81 pens to Kylie, both would have the same number of pens.
Number of pens that each would have in the end
= 100% ÷ 2
= 50%
Number of pens that Jade gave to Kylie
= 77% - 50%
= 27%
27% → 81
1% → 81 ÷ 27 = 3
Number of pens that Kylie had
= 23%
= 23 x 3
= 69
Answer(s): 69
