WebMar 25, 2010 · Solve direct & inverse variation word problems. In this video the instructor teaches about direct and inverse variation. Two variables x and y are said to be in direct variation with each other if you can write them in the form y = K * x. The value of y varies directly corresponding to the value of x. Y is said to be directly proportional to x. WebJan 25, 2024 · Direct and Inverse Variation: Direct and inverse variation can be applied to our day-to-day lives. A proportion tells that two ratios are equal. Four numbers are said to be in proportion if the ratio of the first two numbers is equal to the ratio of the last two numbers. There are two types of proportion: direct and indirect/inverse.
