Answer :

To find 8 numbers between 100 and 500 that are exactly divisible by 9, you can follow these steps:

1. Identify the range you are working with, which is numbers between 100 and 500.
2. Find the first multiple of 9 that is greater than or equal to 100.
3. Continue finding subsequent multiples of 9 until you have identified the first 8 such numbers in this range.

Starting with the initial number slightly above 100, we determine the multiples of 9 consecutively:

1. The smallest multiple of 9 greater than 100:
- 108 (since 100 ÷ 9 gives a quotient of 11 with a remainder, the next multiple is 9 * 12 = 108).

2. The next multiple of 9 after 108:
- 117 (108 + 9).

3. Continue this pattern:
- 126 (117 + 9),
- 135 (126 + 9),
- 144 (135 + 9),
- 153 (144 + 9),
- 162 (153 + 9),
- 171 (162 + 9).

By listing these 8 numbers in sequence:
108, 117, 126, 135, 144, 153, 162, and 171.

These are the first 8 numbers between 100 and 500 that are exactly divisible by 9.
