A camera company routinely ships cameras that have 4 defective cameras for every 800 shipped. Bradley works at a photo shop that sells the cameras to consumers. If Bradley sells 200 cameras, how many can Bradley expect to be defective?

From the information in the problem, the ratio of defective cameras to cameras shipped is [tex] \frac{4}{800} [/tex]. Reducing this ratio, we get the simplified form of

[tex] \frac{4}{800}\div \frac{4}{4}= \frac{1}{200} [/tex]

which, incidentally, gives us our answer. We have 1 defective camera for every 200 cameras shipped.
