Calculating unknown values from two equal ratios may be easy for you but it is not easy for all. Every student has to struggle to understand the process and find their concerned value. Such a relation between two ratios is called a proportion. To make this process easy, you can use a proportion calculator easily with a few steps.
This maths calculator has been designed with a simple interface to let everyone feel comfortable while using it. You can easily use it and solve different problems related to proportion. Doesn’t matter whether you have a complex problem or a simple proportion-related problem, you will be able to solve it using this online tool.

What is meant by Proportion?
Proportion is a mathematical term used to show the equal relationship between two ratios. In simple words, it is a particular relationship that shows the given two ratios are equal to each other. To show two ratios in proportion, two different symbols are used that are given here “::” and “=”.
For example, if you have two ratios p/q and l/m which you want to show in proportion, you can write it as, p/q:: l/m or p/q = l/m.
How to calculate a proportion?
As both ratios involved in a proportion are equal to each other, so, we can solve the problems related to this statement using simple methods. The simplest approach that we can adopt in this regard is cross-multiplication. It is because we have to separate the unknown variable from the given values to find its value.
Here we have solved an example by following the steps you have to follow.
Find the value of “x” if two given ratios are in proportion, 8:15:: x::5.
We can write the given ratios as, By dividing, we get the following factors,
8/15 = x/5
To find the value of “x”, we have to multiply the 5 from its denominator to the other side of the equation.
x 8/15 = x
x = 8/3
