Accepted Solution
We often encounter problems in mathematics where we need to find an unknown quantity. Essentially, these questions involve a missing variable that we need to solve. One of the common problems is in the form of a division quotation like "23 divided by what equals 71?". In this scenario, the "what" represents an unknown variable, often labelled as "x" in mathematics. So, the problem can be reframed as "What is the value of 'x' such that when 23 is divided by it, the result is 71?"
Let's break it down:
Step 1: Set the equation
To accurately represent this problem in the form of an equation, we would write it as:
\[ \frac{23}{x} = 71 \]
The objective of any such problem is to isolate and solve for the variable, in this case, x. The common approach to doing this involves manipulating the equation such that the variable (x) stands alone on one side.
Step 2: Isolate the variable
To do this, we multiply both sides of the equation by x:
\[ 23 = 71 * x \]
Then we isolate x on the right side by dividing by 71:
\[ \frac{23}{71} = x \]
With this, we can solve for x. If needed, we'll round off to three decimal places.
The solution to our equation is therefore:
\[ x = 0.324 \]
