What is 2/4 - 2/3?

What is 2/4 - 2/3?

Here's how to subtract 2/3 from 2/4:

2
4
2
3

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 3, and get 6.

Then we multiply 2 by 4, and get 8.

Next we give both terms new denominators -- 4 × 3 = 12.

So now our fractions look like this:

6
12
8
12

Step 2

Since our denominators match, we can subtract the numerators.

6 − 8 = -2

So the answer is:

-2
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:

-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
3
=
1
