Question

In a computer lab, there are 5 computers for every 10 students. How many computers will be needed for 48 students?

Answer 1

For 10 students, number of computers required = 5
$\therefore$ For 1 student, number of computers required = $\frac{5}{10}=\frac{1}{2}$
$\therefore$ For 24 students, number of computers required = $48\times \frac{1}{2}=24$
Hence, 24 computers are required for 48 students.
