What is 7/14 - 2/4?

Here's how to subtract 2/4 from 7/14:

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 7 by 4, and get 28.

Then we multiply 2 by 14, and get 28.

Next we give both terms new denominators -- 14 × 4 = 56.

So now our fractions look like this:

Step 2
