Question

7. In a survey, the ratio of students who prefer popcorn to potato chips is 3 to 4. If the number of students surveyed who prefer popcom is 360, how many preferred potato chips?

Answer 1

hello

the ratio of popcorn to potato chips is 3:4.

the total number of students surveyed is 360

$\begin{gathered} \text{ratio}=3\colon4\text{ } \\ \text{ number who prefer potato =}\frac{4}{3+4}\times360 \\ \text{potato}=\frac{4}{7}\times360 \\ \text{potato}=\frac{4\times360}{7}=205.71\approx206 \end{gathered}$

from the calculations above, approximately 206 students prefer potato chips to pop corn
