What is 2/8 - 3/12?

What is 2/8 - 3/12?

Here's how to subtract 3/12 from 2/8:

2
8
3
12

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 12, and get 24.

Then we multiply 3 by 8, and get 24.

Next we give both terms new denominators -- 8 × 12 = 96.

So now our fractions look like this:

24
96
24
96

Step 2

Since our denominators match, we can subtract the numerators.

24 − 24 = 0

So the answer is:

0
96
Zero divided by anything is just zero. So that's the final answer:
0
