### Inverse Proportionality: The Rule of Three Inverse ...

It’s an inverse proportionality because as long as A gets bigger, B gets smaller which is exactly what Rule 1 outlines. Additionally, when A is doubled, B is halved (in the second row on the table we can see that A is worth 2 and B, 12). When A triples (going from 1 to 3), B’s value drops from 24 to 8, which is one-third of 24.
