Total number of erasers that Betty and Gabby shared = 100%
If Betty gave 288 erasers to Gabby, 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 Betty gave to Gabby
= 82% - 50%
= 32%
32% → 288
1% → 288 ÷ 32 = 9
Number of erasers that Gabby had
= 18%
= 18 x 9
= 162
Answer(s): 162
