Step 1We 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 15 by 8, and get 120. Then we multiply 2 by 60, and get 120. Next we give both terms new denominators -- 60 × 8 = 480. So now our fractions look like this:

Step 2Since our denominators match, we can subtract the numerators. 120 − 120 = 0 So the answer is:

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