Question

At a college, 7 out of 10 students work either a full-time or a part-time job in addition to their studies. If 4900 students were involved at college, how many students do not have a full-time or part-time job

Answer 1

1470 students do not have a full-time or part-time job

Explanation:

We have a relationship between students who have a part-time job and those who do not. The ratio is 7 out of 10 students.

Then we use this relationship as a conversion factor.

If of 10 students, 7 of them have a job, then of 4900 students, how many of them have a job?

`4900 * (7)/(10)=3430` students

Finally, those who do not have a job are:

`4900- 3430 = 1470`
