What are proportions?
Proportions show a relation between two different ratios. These ration seem different but are actually related in similar way.

Proportion formula:
There is no formula to solve proportions. It is just a matter of writing and simplifying. Say there are two ratios (a) 2:3 and (b) 7:x
To find the value of x in the second proportion:
1. Write the ratios in fraction form.
2. Cross multiply.
3. Separate the x and solve.
This will give the missing value.
How to use the proportion solver?
The application is easy to operate due to its up-to-the-mark useability.
1. Enter the ratios in the correct order, first goes first.
2. Remember to enter the unknown value as x.
3. Click “Calculate”.
Features:
You will understand why the claim is that “This is one of the best proportion solvers” once you install and try it. Its main highlights are:
1. It is to the point with no extra buttons and options to complicate things.
2. The answer is calculated very fast so it is time-saving.
3. Smart color theme which is easy on the eyes.
4. Math keyboard for convenient inputting.
