Hey there, math enthusiasts! Let's dive into a fun little problem today. We're going to hunt down a specific number, and the clues are pretty straightforward. We need to find a number that's a multiple of both 2 and 3, and it has to fall somewhere between 45 and 50. Sounds like a cool challenge, right? It's like a math treasure hunt, where the X marks the spot is a number that follows some specific rules. Understanding multiples is super important in math. It helps with everything from basic arithmetic to more advanced topics like algebra and number theory. So, let's get our detective hats on and start figuring out which number fits the bill. This problem is a great way to reinforce the concept of multiples and get a little practice with mental math. Ready to crack the code? Let's go!

To kick things off, let's clarify what it means to be a multiple of a number. A multiple is simply the result of multiplying a number by an integer (a whole number). For instance, the multiples of 2 are 2, 4, 6, 8, and so on. These numbers are all evenly divisible by 2. Similarly, the multiples of 3 are 3, 6, 9, 12, etc. These numbers are all evenly divisible by 3. Now, when we say a number is a multiple of both 2 and 3, it means it must be divisible by both those numbers. In other words, it must be an even number (divisible by 2) and also be divisible by 3. This leads us to another term: the least common multiple (LCM). The LCM of 2 and 3 is 6, which means any number that's a multiple of both 2 and 3 will also be a multiple of 6. This understanding is key to solving our problem.

So, why is it important to learn about multiples? Well, they're everywhere in math and in real life. Understanding multiples is a building block for many mathematical concepts. In arithmetic, multiples are fundamental to understanding division, fractions, and ratios. In algebra, the concept of multiples extends to polynomials and equations. Outside of the classroom, multiples pop up in various situations. When you're planning a party and need to buy enough plates for everyone, you're dealing with multiples. If you're organizing items into groups, you're using the idea of multiples. Even when you're scheduling events or calculating distances, the concept of multiples often comes into play. Thus, grasping the concept of multiples helps you develop a strong foundation in math, enhancing your problem-solving abilities and preparing you to tackle more complex mathematical challenges. Now let's try to find our mystery number that's a multiple of both 2 and 3 between 45 and 50. We are getting closer to the solution, so let's keep going.

Decoding the Clues: Multiples of 2 and 3

Alright, let's break down the conditions. Our number must be a multiple of 2 and 3. As we've mentioned, if a number is a multiple of both 2 and 3, it is also a multiple of their least common multiple, which is 6. So, we're basically looking for a multiple of 6 that falls between 45 and 50. The multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, and so on. Now, we need to find the one that fits our criteria. Let's look at the numbers between 45 and 50: 46, 47, 48, and 49. Now we need to determine which of these numbers is divisible by both 2 and 3.

Remember, a number is divisible by 2 if it's even, and a number is divisible by 3 if the sum of its digits is divisible by 3. Let's check each number in our range: 46 is even, so it's a multiple of 2, but 4 + 6 = 10, which isn't divisible by 3, so 46 isn't a multiple of 3. 47 isn't even, so it's not a multiple of 2. 48 is even, making it a multiple of 2. Also, 4 + 8 = 12, and 12 is divisible by 3. Therefore, 48 is also a multiple of 3. 49 isn't even, and so it's not a multiple of 2.

So, by process of elimination, we've found our number: 48! It's an even number and therefore a multiple of 2. Also, the sum of its digits (4 + 8 = 12) is divisible by 3, making it a multiple of 3. It's also within the specified range of 45 and 50. The other numbers in the range don't meet both conditions, so our search is successful! Understanding these divisibility rules is super helpful, and it saves a ton of time compared to doing long division every time. In short, mastering these rules makes number theory much more fun and efficient. Keep practicing, and you'll become a pro at spotting multiples in no time.

Solving the Mystery: The Number Unveiled

Drumroll, please... The number we've been hunting for is 48! Congrats if you figured it out along the way! 48 is a fantastic example of a number that beautifully fits the conditions we set. It's divisible by 2 because it's an even number, and it's divisible by 3 because the sum of its digits (4 + 8 = 12) is also divisible by 3. And, of course, it comfortably resides between 45 and 50. This is the beauty of math; there's always a logical path to the answer if we break down the problem into smaller, more manageable steps. It's all about understanding the rules and applying them systematically. Every number is connected in a web of relationships and properties. Multiples, divisors, prime numbers - they are all part of this fascinating world. The fun part is learning how to spot the patterns and use them to solve problems. It's like being a detective, except your tools are numbers and your evidence is logic. Isn't that cool?

So, what have we learned today, guys? We started with the concept of multiples, numbers that can be divided evenly by another number. We specifically focused on multiples of 2 and 3, which brought us to the idea of the least common multiple (LCM). Then, we narrowed our focus to finding a number within a specific range (45 to 50) that met these conditions. Through a process of testing and using divisibility rules, we successfully identified the number 48 as the solution. This little exercise not only helps reinforce the basics of number theory but also demonstrates the importance of logical thinking and problem-solving skills in mathematics. It's all about breaking down a complex problem into simpler steps, and once you get the hang of it, solving these types of problems becomes really enjoyable.

Diving Deeper: Exploring Further

If you enjoyed this little math adventure, here are a few other things you can explore to deepen your understanding: Practice finding multiples of other numbers. Try finding a number that is a multiple of 4 and 5 between 60 and 70. This practice will solidify your understanding of multiples. Learn more about the least common multiple (LCM) and how to calculate it for any set of numbers. It helps in solving many problems related to fractions.
