D. `100%" of "7.5`

Explanation

To find 15% of 50, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the formula for percentage**: To find A% of B, we use the formula:
\[ \text{Percentage} = \frac{A}{100} \times B \]
Here, A is the percentage we want to find (15), and B is the number we are finding the percentage of (50).

2. **Substitute the values into the formula**:
\[ 15\% \text{ of } 50 = \frac{15}{100} \times 50 \]

3. **Simplify the fraction**:
- We can simplify \(\frac{15}{100}\) by dividing both the numerator and the denominator by 5:
\[ \frac{15 \div 5}{100 \div 5} = \frac{3}{20} \]

4. **Multiply by 50**:
\[ \frac{3}{20} \times 50 \]

5. **Perform the multiplication**:
- To multiply \(\frac{3}{20}\) by 50, we can rewrite 50 as \(\frac{50}{1}\):
\[ \frac{3 \times 50}{20 \times 1} = \frac{150}{20} \]

6. **Simplify the result**:
- Now, we can simplify \(\frac{150}{20}\) by dividing both the numerator and the denominator by 10:
\[ \frac{150 \div 10}{20 \div 10} = \frac{15}{2} \]

7. **Convert to decimal**:
- Finally, we can convert \(\frac{15}{2}\) to a decimal:
\[ \frac{15}{2} = 7.5 \]

### Final Answer:
15% of 50 is equal to **7.5**.
