What is 3/11 - 1/4?

Here's how to subtract 1/4 from 3/11:

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 3 by 4, and get 12.

Then we multiply 1 by 11, and get 11.

Next we give both terms new denominators -- 11 × 4 = 44.

So now our fractions look like this:

Step 2

Since our denominators match, we can subtract the numerators.

12 − 11 = 1

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...

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