The ideal mechanical advantage (IMA) of a lever is given by the formula IMA = Le / Lr, where Le is the distance
from the fulcrum to the effort and Lr is the distance from the fulcrum to the resistance.

Write a rational expression representing the IMA of a 5 ft second-class lever of the resistance is placed x ft from the fulcrum
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

IMA = , according to the definition.
