What is the average of the first five multiples of 12?

Answer: To calculate the average of the first five multiples of 12, follow these steps:

  1. Identify the first five multiples of 12:
    The first five multiples of 12 are:

    • 12 \times 1 = 12
    • 12 \times 2 = 24
    • 12 \times 3 = 36
    • 12 \times 4 = 48
    • 12 \times 5 = 60

  2. Sum these multiples:
    $$12 + 24 + 36 + 48 + 60$$
    To get this sum, add the numbers step-by-step:

    • 12 + 24 = 36
    • 36 + 36 = 72
    • 72 + 48 = 120
    • 120 + 60 = 180

    Therefore, the sum of the first five multiples of 12 is 180.

  3. Calculate the average:
    The average of a set of numbers is given by the sum of the numbers divided by the count of the numbers. Here, we have five numbers.

    \text{Average} = \frac{\text{Sum of the multiples}}{\text{Count of the multiples}}
    \text{Average} = \frac{180}{5}
    \text{Average} = 36

Therefore, the average of the first five multiples of 12 is \boxed{36}.

This method involves simple arithmetic operations that are easy to follow, ensuring that even students who are just starting their math journey can understand the process.
