Total number of coins that Erika and Roshel shared = 100%
If Erika gave 74 coins to Roshel, both would have the same number of coins.
Number of coins that each would have in the end
= 100% ÷ 2
= 50%
Number of coins that Erika gave to Roshel
= 87% - 50%
= 37%
37% → 74
1% → 74 ÷ 37 = 2
Number of coins that Roshel had
= 13%
= 13 x 2
= 26
Answer(s): 26
