What is 9/11 - 5/6?

What is 9/11 - 5/6?

Here's how to subtract 5/6 from 9/11:

9
11
5
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 9 by 6, and get 54.

Then we multiply 5 by 11, and get 55.

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

So now our fractions look like this:

54
66
55
66

Step 2

Since our denominators match, we can subtract the numerators.

54 − 55 = -1

So the answer is:

-1
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...

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

There you have it! The final answer is:
9
11
5
6
