I get 100% on the math of writing comparisons as ratios, but this point of confusion remains:
How do we know when we are to first convert to same unit?
For example, the exercise presents 20 questions.
Fourteen compare identical units (mm:mm).
Six compare different units (hours:minutes; hours:day; nickles:dimes).
The answer key indicates that 5 of these need to be converted to identical units (hours:hour) before creating the ratio.
The key indicates that one should be left as is (nickles:dimes).
Is there a way to know? Or is the course just not giving all the info one would normally have?
