Total number of marbles that Pamela and Yoko shared = 100%
If Pamela gave 370 marbles to Yoko, 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 Pamela gave to Yoko
= 87% - 50%
= 37%
37% → 370
1% → 370 ÷ 37 = 10
Number of marbles that Pamela had
= 87%
= 87 x 10
= 870
Answer(s): 870
