Answer:
10%
Step-by-step explanation:
I subtracted the number of total students by the ones that went on the field trip.
350 - 315 = 35
35 students did not go on the field trip.
We can turn this into a fraction:
[tex]\frac{35}{350}[/tex]
[tex]\frac{35}{350}[/tex] = [tex]\frac{1}{10}[/tex]
[tex]\frac{1}{10}[/tex] = 10%
10% of students did not go on the class field trip.
