Total number of erasers that Zoe and Min shared = 100%
If Zoe gave 65 erasers to Min, 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 Zoe gave to Min
= 63% - 50%
= 13%
13% → 65
1% → 65 ÷ 13 = 5
Number of erasers that Zoe had
= 63%
= 63 x 5
= 315
Answer(s): 315
