Total number of coins that Opal and Fanny shared = 100%
If Opal gave 57 coins to Fanny, 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 Opal gave to Fanny
= 69% - 50%
= 19%
19% → 57
1% → 57 ÷ 19 = 3
Number of coins that Opal had
= 69%
= 69 x 3
= 207
Answer(s): 207
