Total number of pens that Erika and Emma shared = 100%
If Erika gave 184 pens to Emma, 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 Erika gave to Emma
= 73% - 50%
= 23%
23% → 184
1% → 184 ÷ 23 = 8
Number of pens that Emma had
= 27%
= 27 x 8
= 216
Answer(s): 216
