Total number of marbles that Cindy and Fanny shared = 100%
If Cindy gave 22 marbles to Fanny, both would have the same number of marbles.
Number of marbles that each would have in the end
= 100% ÷ 2
= 50%
Number of marbles that Cindy gave to Fanny
= 61% - 50%
= 11%
11% → 22
1% → 22 ÷ 11 = 2
Number of marbles that Cindy had
= 61%
= 61 x 2
= 122
Answer(s): 122
