Total number of erasers that Tammy and Nora shared = 100%
If Tammy gave 102 erasers to Nora, 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 Tammy gave to Nora
= 84% - 50%
= 34%
34% → 102
1% → 102 ÷ 34 = 3
Number of erasers that Nora had
= 16%
= 16 x 3
= 48
Answer(s): 48
