Question

[ ] ÷258=45 what is the missing value

Answer 1

We will investigate the missing value under division operation.

The missing value will be represented as a variable ( x ). We can then write down the division of two numbers as follows:

$\frac{x}{258}\text{ = 45}$

We are to solve the above equation by manipulating the entire equation. We will try to isolate the vairable ( x ) on the left hand side of the " = " sign! To do that we will multiply the entire equation by the denominator value as follows:

$258\cdot\frac{x}{258}\text{ = 45}\cdot258$

Simplify the left hand side of the " = " sign as follows:

$\begin{gathered} x\text{ = 45}\cdot258 \\ x\text{ = 11,610} \end{gathered}$

Therefore, the solution to the missing value is:

$11,610\ldots\text{ Answer}$
