Calculate proportions: Cross-multiply fractions, easily, with this simple Android app!
- Enter three numbers into the two fractions.
- Leave empty the number you are looking for.
- Get your results as you type:
- as a sentence
- as a solved equation
I have provided translations for multiple languages. You can use the app in your phone’s native language.
If you spot any translation errors in your language, please email me. I will try to fix it.
There is a small banner ad near the bottom of the screen. Your work will not be interrupted with other annoying ads.
