Q.

400

students attend Ridgewood Junior High School.

2

\% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?

\newline

Answer:

Identify total number of students: Identify the total number of students and the percentage that brings lunch. $\newline$ There are $400$ students in total, and $2\%$ of them bring their lunch to school every day.
Calculate number of students: Calculate the number of students who bring their lunch. $\newline$ To find out how many students bring their lunch, calculate $2\%$ of $400$ . $\newline$ $2\%$ of $400$ = $(2/100) \times 400$
Perform multiplication to find number: Perform the multiplication to find the number of students. $\newline$ egin{equation}(\frac{ $2$ }{ $100$ }) \times $400$ = $0$ . $02$ \times $400$ = $8$ \end{equation} $\newline$ So, $8$ students bring their lunch to school every day.
