    Choose an example of ratios and proportions from the textbook or real life and present a step-by-step solution.

    Example:

    On average 2 out of every 50 CD's in a shipment are defective. Mrs. Synder brought 600 CD's for her store. How many would she expect to be defective?

    Solution:

    Let the number of defective CD's be x then

    2/50 = x/600

    Cross-multiply

    1200 = 50x

    x = 1200/50 = 24 CD's

    She expects 25 CD's to be defective.
