What is 6/9 - 2/3?

Here's how to subtract 2/3 from 6/9:

6
9
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 6 by 3, and get 18.

Then we multiply 2 by 9, and get 18.

Next we give both terms new denominators -- 9 × 3 = 27.

So now our fractions look like this:

18
27
18
27

Step 2

Since our denominators match, we can subtract the numerators.

18 − 18 = 0

So the answer is:

0
27
Zero divided by anything is just zero. So that's the final answer:
0
