Understanding the basics of multiplication
A. Definition of multiplication
In order to fully understand and solve the math riddle “How many 8s are in 100?”, it is essential to have a clear understanding of the concept of multiplication. Multiplication is a basic arithmetic operation that involves combining equal groups or sets to determine the total quantity. It is denoted by the symbol “x” or the asterisk “*”.
The operation of multiplication can be defined as the process of adding a number to itself a certain number of times. For example, 3 x 4 can be understood as adding the number 3 to itself 4 times, resulting in a total of 12. This concept allows for the efficient calculation of larger quantities, making it an essential skill in mathematics.
B. Multiplication as repeated addition
One of the fundamental ways to understand multiplication is through the concept of repeated addition. This means that multiplying two numbers together is equivalent to adding one number repeatedly to itself. For instance, 5 x 3 is the same as adding 5 to itself 3 times, resulting in a total of 15.
By recognizing multiplication as repeated addition, we can break down complex multiplication problems into simpler calculations. This approach allows us to visualize the process and better comprehend the relationships between numbers.
Understanding the basics of multiplication is crucial for solving the riddle “How many 8s are in 100?” as it requires applying this fundamental operation to find the solution. By grasping the definition of multiplication and its connection to repeated addition, we can approach the riddle with a solid foundation of mathematical knowledge.

In the next section, we will explore an alternative approach to finding the answer to this riddle by utilizing division.
Exploring the first approach
A. Breaking down 100 into factors
In order to solve the riddle “How many 8s are in 100?”, one approach is to break down the number 100 into its factors. This involves finding numbers that can be multiplied together to give 100. By breaking down 100 into factors, we can determine how many times the number 8 can fit into each factor and subsequently calculate the total number of 8s in 100.
B. Calculating the number of 8s in each factor
Now that we have the factors of 100, which are 1, 2, 4, 5, 10, 20, 25, 50, and 100, we can calculate the number of 8s in each factor. For example, when we divide 8 by 1, the quotient is 8. Similarly, when we divide 8 by 2, the quotient is 4, and so on. By performing this calculation for each factor, we can determine how many times the number 8 can fit into each of them.
Upon calculating the number of 8s in each factor, we find that 8 can fit into the factors 1, 2, 4, 10, 20, and 25, a total of 6 times. However, it cannot fit evenly into the factors 5, 50, and 100. Therefore, we exclude those factors from our count.
Ultimately, using this approach, we find that there are 6 occurrences of the number 8 in 100. This demonstrates that the answer to the riddle “How many 8s are in 100?” is 6.
Exploring the first approach allows us to understand the process of breaking down numbers into factors and calculating the number of occurrences of a specific number within those factors. This approach showcases the importance of multiplication and its fundamental role in solving math problems.
By breaking down the riddle into factors and considering the number of 8s in each factor, we gain a deeper understanding of multiplication and its application in solving riddles and mathematical problems.

Recap of the Correct Answer
A. Reiterating the Correct Solution to the Riddle
Now that we have explored the basics of multiplication and different approaches to solving the riddle, let’s recap the correct answer. The question “How many 8s are in 100?” is asking how many times the number 8 can be multiplied to get the result of 100.
To find the answer, we can break down 100 into its factors. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
If we calculate the number of 8s in each factor, we can determine how many times 8 can be multiplied to obtain that factor. Starting with the factor 1, which is obviously not divisible by 8, we move on to the factor 2, which also cannot be divided evenly by 8. Continuing this process, we discover that the only factor of 100 that is divisible by 8 is 25.
Therefore, the correct answer to the riddle “How many 8s are in 100?” is 12. We can multiply 8 by 12 to obtain the result of 100.
