Question

In a study of 200 students under 25 years old, 5% have not yet learned to drive. Howmany of the students cannot drive?

Answer 1

We can write 5% in decimal form as 5/100=0.05.

So if a 5% of the 200 students under 25 years old have not yet learned to drive, we can calculate the number of students that have not yet learned to drive as:

$n=\frac{5}{100}\cdot200=5\cdot2=10$

10 students out of the group of 200 can not drive.
