App Description

Calculate proportions using the rule-of-three, easily!

A recipe calls for 200 grams of milk and 300 grams of sugar. How much sugar should you add, if you are using 450 grams of milk?

Answer: 300/200 = X / 450. Solve for X.

Calculate proportions 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, both in sentence form, and as a solved equation.
