Mariana [72]

Answer:

The word problem is " In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there".

Step-by-step explanation:

The given expression is

$8\div \frac{2}{3}$

We need write a word problem which is solved by the above expression.

Word problem : In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there.

Solution:

Let the total number student be x.

$x\times \frac{2}{3}=8$

Divide both sides by 2/3.

$x=\dfrac{8}{\frac{2}{3}}$

$x=\dfrac{8\times 3}{2}$

$x=12$

Therefore, the total number of students is 12.
