What is 6/9 - 4/6?

Here's how to subtract 4/6 from 6/9:

6
9
4
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 6 by 6, and get 36.

Then we multiply 4 by 9, and get 36.

Next we give both terms new denominators -- 9 × 6 = 54.

So now our fractions look like this:

36
54
36
54

Step 2

Since our denominators match, we can subtract the numerators.

36 − 36 = 0

So the answer is:

0
54
Zero divided by anything is just zero. So that's the final answer:
0
