(2/3x=12)
how to solve it...
and there's a question...
Why is x obviously greater than 12?

to solve it you have to divide both sides of the equation by 2/3. On the left the 2/3 cancles with the other 2/3. On the right it is 36/2. Then that leaves x = 36/2
x is obiously greater then 12 because ur multiplying it by a number that is less then one.

To "undo" fractions, you multiply both sides by the reciprocal. Thus:
(2/3)x=12
(3/2)(2/3)x=12(3/2)
The 3/2 and 2/3 cancel on the left.
x = 18
x is obviously larger than 12 because 2/3 is a fraction. So if a fraction (one part of) x is equal to 12 then the whole of x must be larger.

so you should multiply 12 by 3
that makes 2x=36
then u devide 36 by 2 that will left us with 18
x is greater that 12 because when u have 2/3 that is the same as two parts out of three parts.
