What is 5/6 - 8/10?

What is 5/6 - 8/10?

Here's how to subtract 8/10 from 5/6:

5
6
8
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 10, and get 50.

Then we multiply 8 by 6, and get 48.

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

So now our fractions look like this:

50
60
48
60

Step 2

Since our denominators match, we can subtract the numerators.

50 − 48 = 2

So the answer is:

2
60

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:

2
60
÷ 2 =
1
30

Let's try dividing by 2 again...

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

There you have it! The final answer is:
5
6
8
10
=
1
30
