Six twelfths is a fraction which is written as 6/12. If you wish to represent this as thirds then you need to change the denominator (the number you are dividing by) from 12 to 3. You do this by dividing 12 by 4. However as you have made the denominator 4 times smaller, you also have to make the numerator (the number you are dividing) 4 times smaller too in order to maintain the same proportion. 6 divided by 4 is one and a half. So, 6/12 = 1 1/2 / 3. This is known as a complex fraction because (in this case) the numerator contains a fraction.
