What is 6/12 - 2/4?

Here's how to subtract 2/4 from 6/12:

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 6 by 4, and get 24.

Then we multiply 2 by 12, and get 24.

Next we give both terms new denominators -- 12 × 4 = 48.

So now our fractions look like this:

Step 2
