132 : x * 10 = 12
132 : x = 12 : 10
132 : x = 1,2
x = 132 : 1,2
x = 110
132:x x10=12
132x10:x=12
1320:x=12
x=1320:12
x=110
132 : x * 10 = 12
x * 10 = 132 : 12
x * 10 = 11
x = 11/10 (Click cho tớ với nhé!)
132 : x x 10 = 12
x x 10 = 132 : 12
x x 10 = 11
x = 11/10
Ta có: 132 : X x 10 = 12
X x 10 = 132 : 12
X x 10 = 11
X = 11/10
