To find the total number when you're given a part and a percent, you can use the following steps:

**Problem:**  
18 is $$90\%$$ of what number?

**Step 1: Understand the Problem**  
You know that 18 is $$90\%$$ of some number. Let's call that number $$x$$.

**Step 2: Write the Equation**  
The phrase "18 is $$90\%$$ of $$x$$" can be written as:
$$ 18 = 90\% \times x $$

**Step 3: Convert the Percentage to a Decimal**  
Percentages can be converted to decimals by dividing by 100.  
$$ 90\% = \frac{90}{100} = 0.9 $$

**Step 4: Substitute and Solve for $$x$$**  
Now, plug the decimal back into the equation:
$$ 18 = 0.9 \times x $$

To find $$x$$, divide both sides of the equation by 0.9:
$$ x = \frac{18}{0.9} $$

**Step 5: Calculate the Result**  
$$ x = 20 $$

**Answer:**  
18 is $$90\%$$ of **20**.
18 is 90% of 20.
