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 8 by 3, and get 24. Then we multiply 2 by 11, and get 22. Next we give both terms new denominators -- 11 × 3 = 33. So now our fractions look like this:

|||||||||||
Step 2Since our denominators match, we can subtract the numerators. 24 − 22 = 2 So the answer is:

|||||||||||
Step 3Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? To find out, we try dividing it by 2... Nope! So now we try the next greatest prime number, 3... No good. 3 is larger than 2. So we're done reducing. There you have it! The final answer is:
