Question

1 How many students are cleaning 96 desks if each student cleans 4 desks? a) Write an equation using a symbol for the unknown. b) Find the answer to the question and show your reasoning.

Answer 1

Given data:

The numbers of desk clean by a students are 4.

(a)

The expression for the given statement is,

$1\text{ s= 4 d}$

Here, s is the student and d represents desk.

(b)

Multiply 24 on both sides.

$\begin{gathered} 24(\text{ 1 s)=24(4 d)} \\ 24\text{ s =96 d} \end{gathered}$

Thus, for cleaning 96 desks 24 students needed.
