You can find half of anything by multiplying it by 1/2. If the thing youu2019re trying to find half of is a fraction, that means multiplying the denominator by 2. So, half of 8/12 is 8/24, since 12 times 2 is 24.Usually, though, you want to simplify your fractions. You could do that at the end, simplifying 8/24 to 1/3, but I prefer to do it at the start. 8/12 is the same as 2/3. Multiply 2/3 by 1/2 and you get 2/6. Simplify that and you get 1/3. This makes sense intuitively if you think about it: If I have TWO thirds, and I lose half, I am left with ONE third.
