Question 898010
Key idea, RATE, like ration, like RATIO, the comparison of two numbers, usually in the form of a fraction.


One worked 10 hours and earned $85.
Just form a rate with those measures, INCLUDING THE UNITS.  That's all; nothing more complicated.  Form the ratio!


How's this:

{{{(10*hour)/(85*dollars)}}}


{{{(10/85)(hours/dollar)}}}


{{{((2*5)/(5*17))(hours/dollar)}}}


{{{(2/17)(hours/dollar)}}}


Did you want THAT ratio?


If you wanted this the other way, then now you should know what to do.
