Question

What divided by 4 equals 9?

Answer 1

Hint: In this type of question students have to use the concept of multiplication and division. We can solve this question by taking an unknown as a missing term and form an equation and after solving the equation we will reach the required answer. Also whenever we have to maintain equality of an equation perform the same operation on both sides of the equation.

Complete step-by-step answer:
Now our question is ‘What divided by 4 equals 9?’ That means we have to find an unknown number such that the unknown number divided by 4 equals 9. So we replace ‘What’ by an unknown number.
Let us consider the unknown number be \[x\] so we can write,
\[\Rightarrow \left( \dfrac{x}{4} \right)=9\]
Now, by multiplying both sides by 4 we get,
\[\begin{align}
  & \Rightarrow \left( \dfrac{x}{4} \right)\times 4=9\times 4 \\
 & \Rightarrow x=36 \\
\end{align}\]
Hence, we can say that when we divide 36 by 4 we get 9.
Thus, 36 divided by 4 equals 9.

Note: In this type of question students may make mistakes in calculations. Students have to take care when they perform multiplication. Students have to note that, we have to perform multiplication by 4 on both sides to maintain equality. Also students have to take care in understanding the question; we have to find a number such that the number divided by 4 equals 9 and not as 4 divided by the number equals 9. So we have to note that the correct understanding of the question is also important.
