Our Proportion calculator allows you to solve proportion problems and find the missing variable value in a given proportion.

Well, stick to the context to understand how to solve proportions (step-by-step) & with a calculator, basic tips & tricks on solving proportions, & more.

Proportion is said to be a mathematical comparison between two numbers. More specifically, it two sets of the numbers are increasing/decreasing in the same ratio, then the ratios are referred to directly proportional to each other. Typically, proportions are represented with the symbol “\(::\)” or “\(=\)”.

If you want to know the missing variable in the proportion equation, then simply put the equal sign between them. Find the missing value by cross multiplication. Our proportion calculator generates the result with cross-multiplication as well as with the proportion method. Here we have a manual example for clarification.

**Example:**

The equation is given as \(\frac {8}{x} = \frac {6}{4}\), solve for the unknown \(x\)?

**Solution:**

The equation is;

\(\frac {8}{x} = \frac {6}{4}\)

By cross multiplication,

\(6x = 8 \times 4\)

\(x = 8 \times \frac {4}{6}\)

\(x = \frac {32}{6}\)

\(x = 5.33\)

The equation is equal if,

8 / 6 = 1.33

So, it is true that,

x / 4 = 1.33

x = 1.33 × 4

x = 5.33
