What is 11/12 - 2/7?

What is 11/12 - 2/7?

Here's how to subtract 2/7 from 11/12:

11/12 − 2/7

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 11 by 7, and get 77.

Then we multiply 2 by 12, and get 24.

Next we give both terms new denominators -- 12 × 7 = 84.

So now our fractions look like this:

77/ 84 - 24/84

Step 2

Since our denominators match, we can subtract the numerators.

77 − 24 = 53

So the answer is: 53/84
