Total number of marbles that Nicole and Kimberly shared = 100%
If Nicole gave 190 marbles to Kimberly, 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 Nicole gave to Kimberly
= 69% - 50%
= 19%
19% → 190
1% → 190 ÷ 19 = 10
Number of marbles that Nicole had
= 69%
= 69 x 10
= 690
Answer(s): 690
