The "Proportion Calculator" is the first tool in the "mbar School Tools" series.
This App calculates proportions (direct or indirect), also known as "rule of three" by entering three known values and hitting "Calculate". The App will calculate the missing value for you!
A history of calculated values is kept and can be managed within the App.
- mbar School Tools are free to use, have no ads, and will mostly require no special permissions!
