Total number of erasers that Yoko and Emily shared = 100%
If Yoko gave 234 erasers to Emily, both would have the same number of erasers.
Number of erasers that each would have in the end
= 100% ÷ 2
= 50%
Number of erasers that Yoko gave to Emily
= 76% - 50%
= 26%
26% → 234
1% → 234 ÷ 26 = 9
Number of erasers that Yoko had
= 76%
= 76 x 9
= 684
Answer(s): 684
