Question

In a computer lab, there are 3 computers for every 6 students. How many computers will be needed for 24 students?

Answer 1

For 6 student, number of computers required= 3
$\therefore$ For 1 student, number of computers required = $\frac{3}{6}=\frac{1}{2}$
$\therefore$ For 24 students, number of computers required = $24\times \frac{1}{2}=12$
Hence, 12 computers are required for 24 students.
