Total number of coins that Olivia and Kimberly shared = 100%
If Olivia gave 90 coins to Kimberly, 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 Olivia gave to Kimberly
= 65% - 50%
= 15%
15% → 90
1% → 90 ÷ 15 = 6
Number of coins that Kimberly had
= 35%
= 35 x 6
= 210
Answer(s): 210
