Total number of coins that Rachel and Anna shared = 100%
If Rachel gave 217 coins to Anna, 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 Rachel gave to Anna
= 81% - 50%
= 31%
31% → 217
1% → 217 ÷ 31 = 7
Number of coins that Rachel had
= 81%
= 81 x 7
= 567
Answer(s): 567
