Total number of pens that Emma and Xandra shared = 100%
If Emma gave 216 pens to Xandra, 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 Emma gave to Xandra
= 86% - 50%
= 36%
36% → 216
1% → 216 ÷ 36 = 6
Number of pens that Emma had
= 86%
= 86 x 6
= 516
Answer(s): 516
