Cutting Fabric: 100m, 101m, 120m Lengths Puzzle

Hey there, math enthusiasts! Ever stumbled upon a real-world problem that just begged to be solved? Well, today we're diving into a fascinating scenario involving fabric lengths and a curious set of questions. We're going to dissect a problem that asks: If we have fabric pieces measuring 100m, 101m, and 120m, and we want to cut them into smaller, equal pieces, what's the length of each piece, and how many pieces will we get in total? This isn't just a theoretical exercise; it's the kind of challenge that pops up in tailoring, manufacturing, and even DIY projects. So, grab your mental scissors, and let's cut into this problem together!

Delving into the Fabric Dilemma

Okay, guys, let's break this down. The core of the problem lies in figuring out the optimal way to divide three different lengths of fabric – 100m, 101m, and 120m – into equal pieces. Now, the tricky part is that we need to find a common length that can neatly divide all three measurements. This is where our good old friend, the greatest common divisor (GCD), comes into play. The GCD, as you might remember, is the largest number that divides two or more numbers without leaving a remainder. Finding the GCD in this scenario will give us the maximum possible length for each piece of fabric, ensuring we get the fewest possible cuts and minimize wastage. So, the hunt for the GCD begins!

But wait, there's a slight twist! We have three numbers here, not just two. While finding the GCD of two numbers is relatively straightforward using methods like the Euclidean algorithm, dealing with three numbers requires a little more finesse. One approach is to first find the GCD of two of the numbers and then find the GCD of that result with the third number. For instance, we could start by finding the GCD of 100 and 101, and then find the GCD of that result with 120. Alternatively, we could find the GCD of 100 and 120 first, and then find the GCD of that result with 101. The order doesn't matter, as the GCD is associative. The key is to systematically reduce the problem to manageable steps.

Unveiling the GCD: The Key to Equal Pieces

Let's roll up our sleeves and get our hands dirty with the math. To find the GCD of 100, 101, and 120, we'll start by finding the GCD of 100 and 101. Now, 100 and 101 are consecutive numbers, and consecutive numbers are always relatively prime, meaning their only common divisor is 1. So, the GCD(100, 101) = 1. This makes our task significantly easier! Now, we just need to find the GCD of 1 and 120. And guess what? The GCD of 1 and any other number is always 1. Therefore, the GCD(100, 101, 120) = 1. This tells us that the only length that can divide 100m, 101m, and 120m equally is 1 meter. Bummer, right? This means we'll be cutting each fabric piece into individual meters.

Now that we've determined the length of each piece (1 meter), the next part of our puzzle is to figure out how many pieces we'll get from each fabric length. This is a simple division problem. For the 100m fabric, we'll get 100 pieces (100m / 1m = 100 pieces). For the 101m fabric, we'll get 101 pieces (101m / 1m = 101 pieces), and for the 120m fabric, we'll get 120 pieces (120m / 1m = 120 pieces). Easy peasy!

Tallying the Pieces: The Grand Finale

We're almost there, guys! We know how many pieces we'll get from each fabric length. Now, to answer the final part of the question – how many pieces will we get in total? – we simply add up the number of pieces from each fabric: 100 pieces + 101 pieces + 120 pieces = 321 pieces. Voila! We've solved the puzzle. We'll end up with a grand total of 321 pieces of fabric, each measuring 1 meter in length. This whole exercise highlights the importance of the GCD in real-world scenarios where we need to divide things equally and efficiently.
