Total number of pens that Yoko and Natalie shared = 100%
If Yoko gave 125 pens to Natalie, 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 Yoko gave to Natalie
= 75% - 50%
= 25%
25% → 125
1% → 125 ÷ 25 = 5
Number of pens that Yoko had
= 75%
= 75 x 5
= 375
Answer(s): 375
