what are the two forms of one that apply with the conversion 1 lb = 16oz. ?

Question

if you can, please explain what exactly the question means by asking “what are the two forms of 1”

Answer 1

1 lb. = 16 oz.

1 1b./16 oz. or 16 oz./1 lb.   

When you are changing from one unit to another, you use whichever form of 1 is needed to get you to the units you want in your answer. If you have 4 lbs. and want oz. you would multiply by 16 oz./1 lb. If you have 48 oz and you want lb, you'd multiply by 1 lb./16 oz.

Hope that makes sense to you.
