Question 776513: Law of the Lever;
For a system to balance, the product of the weight and its distance from the fulcrum must be the same on each side; that is, (W1*X1)=(W2*X2). This equation is called the law of the lever.
A woman and her son are playing on a seesaw. The boy is at one end, 8 feet from the fulcrum. If the son weighs 100 lb and the mother weighs 125 lb, where should the woman sit so that the seesaw is balanced?

Let's make the son number 1 (and his mother number 2).
= distance from the fulcrum to the mother
--> -->
We can also express that as
or
Or we can say that the mother should sit at 6 feet 5 inches from the fulcrum
, but , and nobody measures fractions of an inch when playing on a seesaw.
