Factor of antiproportionality 0

An antiproportionality is a correlation with constant product.

## Antiproportionalities

## What is an antiproportionality?

An antiproportionality is a correlation which satisfies the following condition: If one value gets higher, the other one gets lower. For example, assume that 6 excavators need 12 hours to dig a hole. Then, 3 excavators would need 24 hours.

## How to calculate with antiproportionalities?

It's easy to see that the product of the values is always the same. This product is called the factor of antiproportionality. In our example, that product equals 72. Knowing that, one can easily calculate that 72 excavators would need 1 hour or one excavator would need 72 hours.
