Hello!

Archimedes Law of the lever says that a lever is balanced if (and only if) the products of the weights and its distances from the pivot are equal.

A seesaw is a typical lever. So if we denote the first distance as `d_1` and the second as `d_2` , then the seesaw will be balanced if

`4*d_1=2*d_2,`

or

`d_2/d_1=2.`
