What is 4/8 - 3/6?

Here's how to subtract 3/6 from 4/8:

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 4 by 6, and get 24.

Then we multiply 3 by 8, and get 24.

Next we give both terms new denominators -- 8 × 6 = 48.

So now our fractions look like this:

Step 2

Since our denominators match, we can subtract the numerators.

24 − 24 = 0

So the answer is:
