What are the Means and Extremes of Proportions? A proportion is just an equation where two ratios are equal, and each piece of the proportion has a special name.
A function is proportional when the output is equal to the input multiplied by a constant. The number of tires is equal to the number of cars times 4. If there are no cars in the parking lot, then the number of tires is 4 times 0, or 0. If there are 3 cars in the lot, the number of tires is 4 times 3.
