Review: Ratio with a Fraction
Explanation
Ratios with two parts are usually best expressed as
fractions. The word "to" can be thought of as delineating the bar of the
fraction. So the ratio of 3 to 
is
To simplify any fraction, we can multiply the top and the
bottom by the same thing, so anything over anything equals 1 and therefore the
action is equivalent to multiplying by 1:
Converting from fraction terminology back to English, this
final fraction is "12 to 1." By comparing the number order of the original
phrase, we see that 12 corresponds to 3 (both are numerators) and therefore 12
to 1 is correct, not 1 to 12.
The correct answer is (A).
