Answer

b. and c. are correct

Work Step by Step

A fraction $\frac{x}{y}$ can also be written in the form $x\div y$, where the numerator of the fraction is being divided by the denominator of the fraction. Therefore, $\frac{2}{5}=2\div5$ $\frac{1}{7}=1\div7$ $\frac{3}{8}=3\div8$ So, b. and c. are in the correct form, and a. is incorrect because it shows the denominator being divided by the numerator.
