Respuesta :

If a student spent 2/7 of an hour each night reading a book, then

[tex]\begin{gathered} \frac{2}{7}\text{ of an hour}\Rightarrow\text{ in one night} \\ 9\cdot\frac{2}{7}\Rightarrow\text{ in nine nights} \end{gathered}[/tex]

So, operating and converting the fraction from improper to mixed

[tex]9\cdot\frac{2}{7}=\frac{18}{7}=2\frac{4}{7}[/tex]

Therefore, the correct answer is

[tex]C.\text{ 2}\frac{4}{7}[/tex]
