Mr. washington is putting his dvds on a shelf that is 10 2⁄3 inches long. if each dvd is 11⁄20 inches wide, how many dvds can he put side-by-side on the shelf?

Here, you just need to take 10 2/3 and divide it by 11/20. You can just stick this into a calculator, or you can do it by hand. If you want to do it by hand the first step is to make 10 2/3 an improper fraction. It'll now be 32/3. Then you'd do 32/3 divided by 11/20. Of course, to do this though you'll have to make the division sign a multiplication sign, and flip the other fraction, so it is its reciprical.

It'll now look like this: 32/3 x 20/11

Then you just multiple straight across and get 640/33.

Simplify and you get 19 and a long decimal.

So, your answer is 19, since you can't have a fraction of a CD.
