What is 5/10 - 3/6?

Here's how to subtract 3/6 from 5/10:

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 5 by 6, and get 30.

Then we multiply 3 by 10, and get 30.

Next we give both terms new denominators -- 10 × 6 = 60.

So now our fractions look like this:

Step 2

Since our denominators match, we can subtract the numerators.

30 − 30 = 0

So the answer is:
