Leap year occurs every four years.

Factors of 110 are 1, 2, 5, 10, 11, 22, 55, and 110.

To answer these questions, let's go step by step:

1. How often does a leap year occur?
A leap year occurs every 4 years. However, there is an exception to this rule. A year that is divisible by 100 is not a leap year unless it is also divisible by 400. So, the simple rule is that if a year is divisible by 4, it is a leap year, unless it is divisible by 100, unless it is also divisible by 400.

2. What are all the prime numbers less than 12?
A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. The prime numbers less than 12 are 2, 3, 5, 7, and 11.

3. What is the eighth multiple of 32, and is the last digit of the multiples of 4 odd or even?
To find the eighth multiple of 32, you would multiply 32 by 8, which gives you 256.
The last digit of any multiple of 4 will always be even. In the case of multiples of 32, since 2 is a factor of 32, the last digit will be a zero.

4. What are the six factors of 12?
To find the factors of 12, we need to determine the numbers that divide evenly into 12. The factors of 12 are 1, 2, 3, 4, 6, and 12.

5. What are the factors of 16?
The factors of 16 are 1, 2, 4, 8, and 16.

6. Two factors of 20 are 1 and 20. What are the four more factors of 20?
We already know that 1 and 20 are factors of 20. To find four more factors, we can divide 20 by numbers greater than 1 and less than 20. The four additional factors are 2, 4, 5, and 10.

7. What are the factors of 11?
The factors of 11 are 1 and 11. Since 11 is a prime number, it only has two factors.

8. What are the factors of 24?
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
