Total number of erasers that Fiona and Kylie shared = 100%
If Fiona gave 370 erasers to Kylie, 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 Fiona gave to Kylie
= 87% - 50%
= 37%
37% → 370
1% → 370 ÷ 37 = 10
Number of erasers that Kylie had
= 13%
= 13 x 10
= 130
Answer(s): 130
