Composed Rule of Three
by: Synergie Apps • 53
Composed Rule of Three is an application for the daily life, which is not always at hand everything you need to perform simple operations like:
"If 3 orange cost 8 dollars, how much do 20 oranges cost?"
Perform rules of three (cross-multiplication), simple or compound, direct or inverse, very quick and easy. As we did in school, and very useful to reinforce concepts and test results for typical exercises:
"A cow gives me two liters of milk in 10 hours, how many hours did it take me 3 cows in 30 liters of milk?"
"A worker takes 3 hours to build a wall, how many workers are needed to build two walls in five hours?"

Awesome app. It has simple, composed, direct and inverse functionality. No other rule of three app does. However the interface is ver slow and dated. Too much pop up windows for options and results.
