Question

during a survey at chute middle school for 7th grade students, 60 out of 80 students surveyed preferred a school lunch over a sack lunch. what percentage of students preferred school lunch?

Explanation:

Step1: Calculate the ratio

The ratio of students who preferred school lunch is $\frac{60}{80}$.

Step2: Simplify the ratio

$\frac{60}{80}=\frac{60\div20}{80\div20}=\frac{3}{4}$.

Step3: Convert to percentage

To convert a fraction to a percentage, multiply by $100$. So, $\frac{3}{4}\times100 = 75\%$.

Answer:

$75\%$
