Here we take a look at how to work with ratios. A ratio is a comparison of two quantities -- the ratio of number x to number y is x/y, where y ? 0. If two quantities are in the ratio a: b, then taking x as a common multiple, the first quantity could be ax and the second one could be bx. We’ll also learn here how to compare more than two quantities at a time and then combine their ratios. For example, if a : b = 3 : 4 and b : c = 6 : 7, then a : b : c = 3 : 4 : 14/3. Once you go through the instructor's explanation in the video, it'll be easy for you to understand how the above ratio was determined.
