Question

What percent of Mr. Liang class spend a 9 to 16 hours each week doing math homework

Answer 1

Step-by-step explanation

To find the percent of her class that spent 9 - 16 hours each week doing math homework, we have to divide the number of people that do their homework that fall in the categories of 9 - 12 and 13 - 16 by the total number of students surveyed and multiply by 100.

That is:

`\begin{gathered} (10+3)/(3+4+5+10+3)*100 \\ \\ (13)/(25)*100 \\ \\ 52\% \end{gathered}`

That is the correct answer.
