Answer:

A. \frac{1}{4} = \frac{3}{12}

Step-by-step explanation:

\frac{1}{4} of the students wore shorts.

\frac{3}{12} of the students wore jeans.

Converting the fractions of the students who wore shorts and jeans respectively;

\frac{1}{4} = 0.25

\frac{3}{12} = 0.25

This means that the ratio of students who wore shorts is the same as that of students who wore jeans.

i.e \frac{1}{4} = \frac{3}{12}
