Total number of pens that Betty and Julie shared = 100%
If Betty gave 32 pens to Julie, both would have the same number of pens.
Number of pens that each would have in the end
= 100% ÷ 2
= 50%
Number of pens that Betty gave to Julie
= 66% - 50%
= 16%
16% → 32
1% → 32 ÷ 16 = 2
Number of pens that Betty had
= 66%
= 66 x 2
= 132
Answer(s): 132
