Total number of beads that Erika and Yoko shared = 100%
If Erika gave 76 beads to Yoko, both would have the same number of beads.
Number of beads that each would have in the end
= 100% ÷ 2
= 50%
Number of beads that Erika gave to Yoko
= 69% - 50%
= 19%
19% → 76
1% → 76 ÷ 19 = 4
Number of beads that Erika had
= 69%
= 69 x 4
= 276
Answer(s): 276
