Question

a student spent 2/7 of an hour each evening reading a book about sailing if it took the student nine evenings to finish the book how many hours in all did the students spend reading 2 4/9 3 4/7 2 4/7

Answer 1

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

`\begin{gathered} (2)/(7)\text{ of an hour}\Rightarrow\text{ in one night} \\ 9\cdot(2)/(7)\Rightarrow\text{ in nine nights} \end{gathered}`

So, operating and converting the fraction from improper to mixed

`9\cdot(2)/(7)=(18)/(7)=2(4)/(7)`

Therefore, the correct answer is

`C.\text{ 2}(4)/(7)`
