Question

Jarrett surveyed elementary school students about their favorite animals at the zoo He displayed his results in this circle graph If 412 students chose lions as their favorite zoo animal how many total students did Jarrett survey?

Answer 1

Since the 40% of the students choose lion, we can use the following expression:

$\begin{gathered} \text{Total of students}\cdot\frac{\text{percent}}{100}=\text{equivalent number to the percent} \\ \text{Total students}\cdot\frac{40}{100}=412 \\ \text{Isolating the variable total students:} \\ \text{Total students=}\frac{412\cdot100}{40}=\frac{41200}{40} \\ \text{Total students=1030} \end{gathered}$

Jarrett survey 1030 students
