Total number of coins that Shiyun and Dana shared = 100%
If Shiyun gave 39 coins to Dana, 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 Shiyun gave to Dana
= 63% - 50%
= 13%
13% → 39
1% → 39 ÷ 13 = 3
Number of coins that Dana had
= 37%
= 37 x 3
= 111
Answer(s): 111
