Single Rule of Three Inverse
Calculate proportions with inverse rule of three
The rule of three inverse is used when two quantities are inversely proportional to each other. If a is to b as c is to x (inversely), then x = (a × b) ÷ c
If A is to B as C is to X (inversely), then X = ?
Example: If 5 workers take 10 days to complete a job, how many days will 10 workers take?
