ProportionsOf ?
Rule of Three Solver
Free · Designed for iPad. Not verified for macOS.
Cross-multiplication or Means-Extremes Property of Proportions:
In maths we say: The product of the means is equal to the product of the extremes:
∴ x:z = y:w => x.w = z.y
This APP uses the Rule of Three to calculates the ratio between values.
For example, you can calculate whether it's worth buying a promotional product like this one:
"Buy 70gr of biscuit for €4.98 or 140gr for € 9.97".
Would not it be more advantageous to buy 2 of 70g instead of 1 package of 140g?
Well, you can draw your own conclusions using the app for a multitude of calculations.
Basically, the entire world around your is a matters of proportions.
The App also a great tool for children to get a notion of how they can calculate proportions using the rule of three to start to use on their daily-life.
