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= $3$

Using Unitary Method,

Number of computers required for $1$ student = $\frac{3}{6}=\frac{1}{2}$

$\therefore$ Number of computers required for $24$ students = $24\times \frac{1}{2}=12$

Hence, $12$ computers are required for $24$ students.
