Total number of erasers that Jean and Nicole shared = 100%
If Jean gave 22 erasers to Nicole, 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 Jean gave to Nicole
= 61% - 50%
= 11%
11% → 22
1% → 22 ÷ 11 = 2
Number of erasers that Jean had
= 61%
= 61 x 2
= 122
Answer(s): 122
