Total number of erasers that Esther and Sabrina shared = 100%
If Esther gave 150 erasers to Sabrina, 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 Esther gave to Sabrina
= 80% - 50%
= 30%
30% → 150
1% → 150 ÷ 30 = 5
Number of erasers that Sabrina had
= 20%
= 20 x 5
= 100
Answer(s): 100
