Total number of beads that Emily and Tina shared = 100%
If Emily gave 290 beads to Tina, 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 Emily gave to Tina
= 79% - 50%
= 29%
29% → 290
1% → 290 ÷ 29 = 10
Number of beads that Tina had
= 21%
= 21 x 10
= 210
Answer(s): 210
