Jawab:
0,2525... = a
25,2525... = 100a
25,2525... - 0,2525... = 100a - a
25 = 99 a
a = 25/99
Misal :
a = 0,25252525 ........
karena dua digit berulang, maka dikalikan dengan angka 100, menjadi :
100a = 25,252525 ........
100 a - a = 25,252525...... - 0,25252525
99 a = 25
Jadi Pecahan biasanya = 25 / 99
