Understanding Inverse Proportion

Inverse proportion, also known as indirect proportion, describes a relationship between two quantities where if one quantity increases, the other decreases proportionally. For example, if you increase the number of workers on a job, the time required to complete the job usually decreases, assuming they work at the same rate. Mathematically, if 'a' and 'b' are inversely proportional, their product is constant (k), i.e., a * b = k. This calculator helps you find the missing value in such relationships. Simply input three known values to calculate the fourth in an inverse proportion scenario.

Formula: a * b = c * d
Use Case: Time and speed, workers and time to complete a task, etc.
Example: If 4 workers can build a wall in 6 hours, how long would it take 3 workers? (4 * 6 = 3 * x, x = 8 hours).
