Question

There are 30 students in a Grade 8 class. One-third of the students take a school bus, ⅕ take public transportation, ⅙ are driven by family, and the rest walk to school.
a) What fraction of the students in the class walk to school?
b) How many of the students in the class walk to school?

Answer 1

Answer:

a) 3/10 b) 9

Step-by-step explanation:

a) No. of students = 30

No. of students taking bus = 1/3*30 = 10

No. of students taking public transport = 1/5*30 = 6

No. of students driven by family = 1/6*30 = 5

No. of students left = 30-10+6+5 = 30-21 = 9

Fraction of students who walk to school = 9/30 = 3/10

b)No. of students who walk to school = 3/10*30 = 9
