In subtracting two fractions, it must be noted that they first must have a common denominator. In order to find the least common denominator, check first if two fractions are a factor of one another, and if not the two fraction can be multiplied by one another in order to find their LCD.
In this case, 12 is factorable by 3 meaning that their LCD is 12.
Equating the whole solution, we first divide 12 by 12 since it is the denominator, and multiply the answer to the numerator.
12/12 = 1
1 x 11 = 11
Next divide 12 by 3 and multiply it to the numerator
12 / 3 = 4
4 x -2 = -8
Now the solution can be easily solved.
= 11 / 12 - 8 / 12
= 3/12 or 1 / 4 or 0.25
