What is 2/4 - 2/6?

What is 2/4 - 2/6?

Here's how to subtract 2/6 from 2/4:

2
4
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 2 by 6, and get 12.

Then we multiply 2 by 4, and get 8.

Next we give both terms new denominators -- 4 × 6 = 24.

So now our fractions look like this:

12
24
8
24

Step 2

Since our denominators match, we can subtract the numerators.

12 − 8 = 4

So the answer is:

4
24

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
24
÷ 2 =
2
12

Let's try dividing by 2 again...

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

2
12
÷ 2 =
1
6

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:
2
4
2
6
=
