x = 0.75 * 9

Calculating the equation, we find:

x = 6.75

Therefore, the unknown number is 6.75.

Step-by-Step Guide to Finding the Answer:
To provide a clear understanding, let’s go through the step-by-step process of finding the unknown number.

Step 1: Write down the given information.
In this case, we are given that 9 is 75% of a certain number.

Step 2: Set up the equation.
Using the formula mentioned earlier:
x = (Percentage / 100) * Total number

Substituting the given values:
x = (75 / 100) * 9

Step 3: Simplify the equation.
Multiply 75 by 9 and divide it by 100:
x = 6.75

Step 4: Solve for the unknown number.
The unknown number is 6.75.
