The numbers of desk clean by a students are 4.
(a)
The expression for the given statement is,
[tex]1\text{ s= 4 d}[/tex]Here, s is the student and d represents desk.
(b)
Multiply 24 on both sides.
[tex]\begin{gathered} 24(\text{ 1 s)=24(4 d)} \\ 24\text{ s =96 d} \end{gathered}[/tex]Thus, for cleaning 96 desks 24 students needed.
