If lemonade costs $0.52 per pint, what is the cost per cup?
$0.26 per cup
The “units” will be $/cup. The math will be conversion of pints to cups. There are 2 cups in a pint (you can look that up -or Google it). So our conversion ratio value is:
Applying that to our known value we need to divide in order to get the dimensions correct:
($0.52/pint)/(2cups/pint) to arrive at $0.26/cup.
Remember – the MATH will always give you some number! For it to be correct and useful, you need to make sure that the dimensions describe what you want.
