Solving The Math Riddle: Finding The Unknown Number

by ADMIN 52 views

Hey guys! Let's crack this fun math riddle together. It's like a little puzzle, and we'll use some simple steps to figure out the secret number. This is a great way to brush up on your math skills and understand how equations work. So, get ready to put on your thinking caps and let's dive in! The riddle goes like this: "A student thought of a number. If 12 is added to it, and then the result is divided by 6, we get 9. What number did the student think of?"

Breaking Down the Problem: Understanding the Riddle

Alright, first things first, let's break down what the riddle is telling us. It’s like a secret code, and we need to decipher it! The core of the problem is that there's a hidden number, the one the student thought of. We don't know what it is yet, so we'll call it 'x'. The riddle then gives us a series of instructions that have been applied to this number:

  • Addition: First, 12 is added to our secret number (x + 12). This is our initial operation.
  • Division: Next, the result of that addition is divided by 6 ((x + 12) / 6). So, whatever you get from adding 12 to our number, you then split that by 6.
  • The Outcome: The riddle tells us that after all that, the final result is 9. This means our series of operations have resulted in the number 9. This is like the final clue in a detective story.

So, the riddle transforms into this basic equation: ((x + 12) / 6) = 9. Our mission is to turn this equation back into our secret number, the 'x'. It seems a bit complex, but don't worry, we will solve it step-by-step. The key is to work backward. We'll undo each step, in reverse order, until we reveal our mystery number. Keep in mind that these kind of riddles are meant to test our logical thinking skills and also enhance our understanding of the basic arithmetic operations. We will be using the opposite operation to find the answers.

Visualizing the Steps

Think of it like this. Imagine you have a box. You put a number in it (our secret number). Then you add 12 to it. And then you divide everything in the box by 6. And at the end of the process, you get the number 9.

  • Start: Unknown number (x)
  • Step 1: Add 12 (x + 12)
  • Step 2: Divide by 6 ((x + 12) / 6)
  • End Result: 9

Our goal is to reverse this process to find what number was initially in the box. Let's move on to finding the number, shall we?

Reversing the Operations: Unveiling the Secret Number

Okay, now for the fun part! To find the number the student thought of, we're going to reverse the operations. Remember, we worked forward to get to 9, now we will work backwards to find out what that initial number was. We will take the final result and 'undo' the operations that were done to the secret number. So, let’s start from the end and work our way back to the beginning. This is like retracing your steps to find a hidden treasure.

  1. Undo the Division: The last operation was dividing by 6. To undo this, we'll do the opposite – we'll multiply by 6. We know that the result of the division was 9, so we multiply 9 by 6: 9 * 6 = 54. This tells us that before the division, the number was 54.
  2. Undo the Addition: Now we go back to the step before the division. Before we divided by 6, we added 12 to our secret number. To undo this, we'll subtract 12 from 54: 54 - 12 = 42. And there you have it, guys! The number the student originally thought of was 42! We have successfully completed our mission.

So, by reversing the steps, we've found the unknown number. We started with the final result, 9, and worked backward to find the initial number. We basically went back through the steps in reverse order, each time doing the opposite operation.

Step-by-Step Breakdown

  • Final Result: 9
  • Reverse Division: 9 * 6 = 54
  • Reverse Addition: 54 - 12 = 42
  • Solution: x = 42

Isn't it cool how we can figure out the hidden number just by doing the opposite of what was done in the beginning? This is a basic illustration of how we use inverse operations in math.

Verifying the Solution: Making Sure We Got It Right

Alright, now that we've found our answer, let's double-check it to make sure we're correct. There is no point in getting the answer if we do not confirm that it is correct. This is called verifying the solution and we can verify it by plugging the number we think it is, back into the original problem. We plug 42 back into the equation to confirm whether it’s correct. We use the original steps to confirm that 42 is the correct number. This is like putting all the puzzle pieces together and making sure they fit perfectly.

  1. Start with the Number: We start with the number 42.
  2. Add 12: Add 12 to 42: 42 + 12 = 54.
  3. Divide by 6: Divide the result by 6: 54 / 6 = 9.
  4. The Outcome: Does it match the original riddle? Yes, it does. We were told that the final answer would be 9, and it is indeed 9. This means our solution is correct!

This step is super important in math. It helps us make sure we didn't make any mistakes along the way. By verifying our answer, we ensure that the number satisfies the conditions set in the riddle. This ensures that our solution is accurate and that we fully understand the problem. So, when you are in a test, always remember to double-check, so you will not miss any points.

Verification in Action

  • Start: 42
  • Add 12: 42 + 12 = 54
  • Divide by 6: 54 / 6 = 9
  • Matches the Riddle: Yes!

Since the steps of our confirmation matched the riddle's condition perfectly, we are sure that we found the right answer. This method of verifying answers is helpful in numerous areas of math and science.
