![]() The law of multiple proportions is one of the most fundamental rules of stoichiometry, discovered by the British chemist John Dalton. The ability to solve proportions may also come in handy when dealing with chemical reactions. This time, let's have a look at the formula for the distance: Now, we will talk about an example of the constant of proportionality of two inversely proportional variables. In both of these examples, the directly proportional variables are mass and volume. Other popular examples of constants of proportionality of two directly proportional variables are concentration and density. The other way around, when the distance becomes shorter, then the time value will also have to decrease to maintain the constant ratio. With the value of time gradually increasing, the distance covered will also rise proportionally. This way, by knowing our speed, we can also calculate the distance we will cover in 1 minute, 1 hour, 1 day, or any other period. ![]() As this relationship is (by proportion definition) constant, then if we change one variable, the second one will also have to change. Looks familiar, doesn't it? Yes, it is the same formula as for the constant of proportionality of two directly proportional variables. Where v v v is the velocity, s s s is the distance, and t t t stands for time. What is the process if we want to simplify or scale the proportion up to a larger, yet equivalent proportion? The next section on how to solve proportions explains this process. Note that this proportion calculator will not represent the proportion in the latter form. If you wish to rewrite this proportion using a colon, you could write it as 7 : 12 7:12 7 : 12. You want to know the proportion of slices remaining compared to the entire cake. 5 of the 12 slices have been eaten (by that cheeky uncle). Suppose, that there is a cake cut into 12 slices. To illustrate this, let's look at an example. The upper number of proportion is the numerator, and the bottom part of the proportion is the denominator. Just as a fraction is made up of two parts, a numerator and a denominator, the same holds true for a proportion. It still follows the proportion definition but also enables you, for example, to calculate what percent of your birthday cake was eaten by your uncle □. If your preference is in the percent-based display, we encourage you to visit our percentage calculator, it might also be a better choice for solving proportions with 100 100 100as the denominator. ![]() The result is typically seen as a fraction, but can also be represented with a colon, or as a decimal or percent. It displays what portion of one part is contained in the whole. A proportion is a relationship between two quantities.
