Total number of marbles that Nora and Pamela shared = 100%
If Nora gave 74 marbles to Pamela, 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 Nora gave to Pamela
= 87% - 50%
= 37%
37% → 74
1% → 74 ÷ 37 = 2
Number of marbles that Pamela had
= 13%
= 13 x 2
= 26
Answer(s): 26
