About this app

A very simple utility to help you in your everyday life calculating the unknown quantity in proportions.

Select where to put the x, insert values on which you want to calculate proportions then touch the "Calculate" button.

That's all!

This app is not intended to doing complex calculations (e.g. multiple unknown quantities) or to solve the proportions in place of the students showing them all the steps.
