SOLUTION: A store received a shipment of stuffed animals. The stockperson placed 1/5 of them on the shelves, leaving 280 of them in storage. How many of the items were in the shipment?

Let n be the answer.

If one fifth of the n animals are placed on the shelves, then the
other four fifths of the n animals must be those remaining 280.

So we ask

4/5 ths of what equals 280?

4/5 ths of n equals 280

or



Multiply both sides by 5



Divide both sides by 4
