Question

Out of 350 students. 3 15 went on the class field trip. What percent of the students did not go on the class field trip?

Answer 1

In total we have 350 students

315 went on the class field trip

In order to know how many students did not go on the class field trip

350-315=35

if

350--- 100%

35 --- x

where x is the percentage of students did not go on the class field trip

$x=\frac{35\times100}{350}=\frac{3500}{350}=10$

the percentage of students did not go on the class field trip is 10%
