A Big Burger has 1/4 pound of meat and a superburger has 1/3 pound of meat. How much more meat is used for the superburger?

The superburger contains ##1/12## pound more meat than the Big Burger.

We represent the extra meat in the superburger by ##x##. The equation will be:

##x=1/3-1/4##

Multiply all factors by ##12## and simplify.

##12x=4-3##

##12x=1##

Divide both sides by ##12##.

##x=1/12##
