Write all the multiples of 9 upto 100.

Answer

To find all the multiples of 9 up to 100, we will multiply 9 by whole numbers starting from 1 and continue until the product exceeds 100. Here’s how we can do it step by step:

### Step-by-Step Solution:

1. **Start with the first multiple of 9:**
- Multiply 9 by 1.
- \( 9 \times 1 = 9 \)

2. **Continue multiplying by the next whole numbers:**
- \( 9 \times 2 = 18 \)
- \( 9 \times 3 = 27 \)
- \( 9 \times 4 = 36 \)
- \( 9 \times 5 = 45 \)
- \( 9 \times 6 = 54 \)
- \( 9 \times 7 = 63 \)
- \( 9 \times 8 = 72 \)
- \( 9 \times 9 = 81 \)
- \( 9 \times 10 = 90 \)
- \( 9 \times 11 = 99 \)

3. **Check the next multiple:**
- \( 9 \times 12 = 108 \) (This is greater than 100, so we stop here.)

4. **List all the multiples found:**
- The multiples of 9 up to 100 are:
- 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.

### Final Answer:
The multiples of 9 up to 100 are: **9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.**
