What is 6/8 - 8/11?

Here's how to subtract 8/11 from 6/8:

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 6 by 11, and get 66.

Then we multiply 8 by 8, and get 64.

Next we give both terms new denominators -- 8 × 11 = 88.

So now our fractions look like this:

Step 2

Since our denominators match, we can subtract the numerators.

66 − 64 = 2

So the answer is:

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

Let's try dividing by 2 again...

No good. 2 is larger than 1. So we're done reducing.
