Question

60 students were sick. If the ratio of students who had the flu to students who did not hove thee flu was 41, how many students had the flu?

Answer 1

Since there are 4 sick students with flu for each sick student with other illness, then, there are 4 students with flu for each 5 sick students.

Multiply the ratio 4:5, which is the proportion of students with flu to sick students, by the total amount of sick students, to find how many students had the flu:

$\frac{4}{5}\times60=48$

Therefore, 48 students had the flu.
