Total number of marbles that Zara and Gillian shared = 100%
If Zara gave 184 marbles to Gillian, 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 Zara gave to Gillian
= 73% - 50%
= 23%
23% → 184
1% → 184 ÷ 23 = 8
Number of marbles that Zara had
= 73%
= 73 x 8
= 584
Answer(s): 584
