1/2-1/4= We have to make sure the denominators are equal. Since 2 is evenly divided by 4, we can multiply just one term to get a common denominator.

Multiply 1 by 2, and get 2, then we multiply 2 by 2 and get 4. So now our fractions look like this:

2
4
+
1
4
Step 2
Since our denominators match, we can add the numerators.

2 + 1 = 3

So the answer is:

3/4
