Nik has 200 crayons. He wants to separate them into groups of 8 and put them into boxes.  Each box weighs 8 ounces. Each crayon weighs 1 ounce. If he puts all of his crayons into boxes, what is the total weight, in pounds, of the crayons and the boxes, when there are 16 ounces to a pound?
First find how many boxes Nik needs. 200 crayons / 8 crayons per box = 
<gadget id="calculator">200/8</gadget>
<output>25</output>
25 boxes.
25 boxes * 8 ounces per box = 
<gadget id="calculator">25*8</gadget>
<output>200</output>
200 ounces.
Each crayon weighs 1 ounce, so 200 + 200 = 
<gadget id="calculator">200+200</gadget>
<output>400</output>
400 ounces.
400 ounces / 16 ounces per pound = 
<gadget id="calculator">400/16</gadget>
<output>25</output>
25 pounds.
