Answer 3

Finding Two Three-Digit Numbers Divisible by 3 but Not by 2

To find two three-digit numbers that are divisible by 3 but not by 2, we can start by listing the three-digit numbers that are divisible by 3 and then filter out those that are also divisible by 2. Let's proceed with this approach.

Three-Digit Numbers Divisible by 3

The three-digit numbers divisible by 3 are those whose sum of digits is divisible by 3. For example, 102, 105, 108, etc., are all divisible by 3.

Three-Digit Numbers Divisible by 3 and 2

We need to filter out the numbers that are also divisible by 2. This means we need to exclude numbers with an even last digit, as any number with an even last digit is divisible by 2.

Finding the Numbers

Let's find two three-digit numbers that are divisible by 3 but not by 2:

1. The first number: 105. The sum of its digits (1 + 0 + 5) is 6, which is divisible by 3 but it's not divisible by 2. - Source: 2. The second number: 123. The sum of its digits (1 + 2 + 3) is 6, which is divisible by 3 but it's not divisible by 2. - Source: So, the two three-digit numbers that are divisible by 3 but not by 2 are 105 and 123.
