What is 5/11 - 2/6?

What is 5/11 - 2/6?

Here's how to subtract 2/6 from 5/11:

5
11
2
6

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 2 by 11, and get 22.

Next we give both terms new denominators -- 11 × 6 = 66.

So now our fractions look like this:

30
66
22
66

Step 2

Since our denominators match, we can subtract the numerators.

30 − 22 = 8

So the answer is:

8
66

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:

8
66
÷ 2 =
4
33

Let's try dividing by 2 again...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

No good. 5 is larger than 4. So we're done reducing.

There you have it! The final answer is:
5
11
2
6
=
4
