Given information:

  1x12x2

Formula used:

Properties of fractions:- ACBC=ABC

Properties of fractions :- AB÷CD=AB.DC

Calculations:

Numerator = 1x12

Writing fraction in form of LCD (least common denominator)

  =22xx2x=2x2x (i)

Denominator = x2  (ii)

Now,

  =2x2x÷(x2)1=2x2x.1(x2)=(x2)2x.1(x2)

  =12x ( by cancelling (x2) )

After simplifying we get 12x .
