No, a proportion does not have to have an unknown. A proportion is simply a statement that two ratios are equal, which can be expressed with known values. However, in many mathematical problems, proportions are used to solve for an unknown variable, making them a common tool in such cases.

In statistics what is Pi used for?
In statistics, pi represents the population proportion of successes. Using p, the sample proportion of successes, inferences can be made about pi, although it is usually unknown.
What to do when you have 2 Numbers in a proportion?
When you have two numbers in a proportion, you can use cross-multiplication to find the unknown value or confirm the relationship. Set up the proportion as a fraction (a/b = c/d) and cross-multiply to get ad = bc. If you're solving for a missing number, isolate that variable and solve the equation. Lastly, ensure the proportion remains valid by checking if the ratios are equal.
What is the meaning of ratio and proportions?
A ratio is a comparison of two numbers. We generally separate the two numbers in the ratio with a colon (:). Suppose we want to write the ratio of 8 and 12.We can write this as 8:12 or as a fraction 8/12, and we say the ratio is eight to twelve while A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.3/4 = 6/8 is an example of a proportion.When one of the four numbers in a proportion is unknown, cross products may be used to find the unknown number. This is called solving the proportion. Question marks or letters are frequently used in place of the unknown number.

How do you express a proportion?
A proportion is expressed as an equation that states two ratios are equal, typically written in the form ( \frac{a}{b} = \frac{c}{d} ). This means that the relationship between the quantities ( a ) and ( b ) is the same as the relationship between ( c ) and ( d ). Proportions can also be represented using a colon, such as ( a:b = c:d ). To solve a proportion, you can use cross-multiplication to find an unknown value.

How do you solve the proportion of something?
There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.
