6ab:ab=25
(600+ab):ab=25
600:ab+ab:ab=25
600:ab+1=25
600:ab=25-1
600:ab=24
ab=600:24
ab=25
Vậy ab=25
TK CHO MK NHÉ THANK YOU
Ta có:
6ab:ab=125
(600+ab):ab=25
600:ab+ab:ab=25
600:ab+1=25
600:ab=25-1
600:ab=24
ab=600:24
ab=25
Vậy a=2; b=5
6ab : ab = 25
( 600 + ab) x 1/ab = 25
600 x 1/ab + ab x 1/ab = 25
600 x 1/ab + 1 = 25
600/ab = 24
ab = 25
