`100%" of "x" is equal to "_________.`

Options

A. `100x`
B. `0.1x`
C. `0.01x`
D. `x`

Explanation

To find out what "100% of x" is equal to, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Percentage**:
- Percentages are a way to express a number as a fraction of 100.
- For example, A% of B can be calculated using the formula:
\[ \text{A% of B} = \frac{A}{100} \times B \]

2. **Apply the Formula**:
- In this case, we want to find "100% of x".
- Using the formula, we substitute A with 100 and B with x:
\[ 100\% \text{ of } x = \frac{100}{100} \times x \]

3. **Simplify the Expression**:
- Calculate \(\frac{100}{100}\):
\[ \frac{100}{100} = 1 \]
- Now, substitute back into the equation:
\[ 100\% \text{ of } x = 1 \times x \]

4. **Final Result**:
- Since multiplying by 1 does not change the value, we have:
\[ 100\% \text{ of } x = x \]

### Conclusion:
Thus, "100% of x" is equal to **x**.
