201,ab : 126 = 1,ab
=> 201ab : 126 = 1ab
126 x 1ab = 201ab
12600 + 126 x ab = 20100 + ab
126 x ab = 7500 + ab
125 x ab = 7500
ab = 7500 : 125
ab = 60
Vậy : a = 6 ; b = 0
1,ab x 126 = 201,ab
( 100 + ab ) x 126 = 20100 + ab
12600 + 126ab = 20100 + ab
126ab - ab = 20100 - 12600
125ab = 7500
=> ab = 7500 : 125
=> ab = 60
