Total number of marbles that Tina and Natalie shared = 100%
If Tina gave 117 marbles to Natalie, 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 Tina gave to Natalie
= 89% - 50%
= 39%
39% → 117
1% → 117 ÷ 39 = 3
Number of marbles that Natalie had
= 11%
= 11 x 3
= 33
Answer(s): 33
