Answer

To solve the question "What is the value of thirty percent of twenty-five percent of 1320?", we can break it down into steps.

### Step-by-Step Solution:

1. **Convert percentages to fractions**:
- Thirty percent (30%) can be written as \( \frac{30}{100} \).
- Twenty-five percent (25%) can be written as \( \frac{25}{100} \).

2. **Calculate twenty-five percent of 1320**:
- First, we find \( 25\% \) of \( 1320 \):
\[ 25\% \text{ of } 1320 = \frac{25}{100} \times 1320 \]
- Simplifying \( \frac{25}{100} \):
\[ \frac{25}{100} = \frac{1}{4} \]
- Now, calculate \( \frac{1}{4} \times 1320 \):
\[ \frac{1320}{4} = 330 \]

3. **Calculate thirty percent of the result from step 2**:
- Now, we need to find \( 30\% \) of \( 330 \):
\[ 30\% \text{ of } 330 = \frac{30}{100} \times 330 \]
- Simplifying \( \frac{30}{100} \):
\[ \frac{30}{100} = \frac{3}{10} \]
- Now, calculate \( \frac{3}{10} \times 330 \):
\[ \frac{3 \times 330}{10} = \frac{990}{10} = 99 \]

4. **Final answer**:
- Therefore, the value of thirty percent of twenty-five percent of 1320 is **99**.
