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 =}(4)/(3+4)*360 \\ \text{potato}=(4)/(7)*360 \\ \text{potato}=(4*360)/(7)=205.71\approx206 \end{gathered}

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