What is 5/6 - 1/2?

What is 5/6 - 1/2?

Here's how to subtract 1/2 from 5/6:

5
6
1
2

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 2, and get 10.

Then we multiply 1 by 6, and get 6.

Next we give both terms new denominators -- 6 × 2 = 12.

So now our fractions look like this:

10
12
6
12

Step 2

Since our denominators match, we can subtract the numerators.

10 − 6 = 4

So the answer is:

4
12

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:

4
12
÷ 2 =
2
6

Let's try dividing by 2 again...

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

2
6
÷ 2 =
1
3

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
1
2
=
