Step 1: Dividing by 2
When it comes to finding half of a number, the first step is to divide the number by 2. This may seem like a simple task, but let’s break it down and understand the process.
Explain the first step of dividing 136 by 2
To find half of 136, we need to divide it by 2. Dividing a number by 2 is equivalent to splitting it into two equal parts. In this case, we want to determine what number, when multiplied by 2, will give us 136.
To perform the division, we can use long division or a calculator. Let’s use a calculator for simplicity. When we divide 136 by 2, we get the result 68. So, 68 is half of 136.
Provide a simple example of dividing an even number by 2
Let’s take a simpler example to understand the concept better. Suppose we want to find half of 20. We divide 20 by 2, and the result is 10. Therefore, 10 is half of 20.
Dividing an even number by 2 is straightforward because even numbers are divisible by 2 without any remainder. However, when dealing with odd numbers, we may encounter remainders.
For instance, if we want to find half of 25, we divide it by 2. The result is 12.5. In this case, we get a decimal value because 25 is an odd number. The decimal value represents half of 25.
Remember, when dividing an odd number by 2, we may end up with a decimal value. It’s essential to understand this concept to accurately find half of any number.
By following this simple step of dividing a number by 2, we can determine its half. This is a fundamental concept in mathematics and has practical applications in various real-life scenarios.
Understanding how to divide a number by 2 lays the foundation for solving more complex mathematical problems. It is a skill that can be applied in everyday life, from splitting expenses with friends to calculating discounts during shopping.

Step 3: Solving the Equation
In the previous steps, we have learned how to divide a number by 2 and simplify the calculation. Now, let’s move on to the next step – solving the equation. Solving the equation will give us the final result, which is half of 136.
Demonstrate how to solve the division equation
To solve the division equation, we will use the result from the previous step, which is 68. The equation we need to solve is:
136 ÷ 2 = ?
To find the answer, we need to divide 136 by 2. Dividing 136 by 2 can be done by performing long division. Let’s go through the steps:
Start by dividing the first digit of 136, which is 1, by 2. Since 1 is less than 2, we need to bring down the next digit, which is 3. So, we have 13.
Now, divide 13 by 2. The result is 6 with a remainder of 1. Write down the 6 above the line and the remainder, 1, to the right of the line.
Bring down the next digit, which is 6, and divide it by 2. The result is 3 with no remainder. Write down the 3 above the line.
Finally, bring down the last digit, which is 6, and divide it by 2. The result is 3 with no remainder. Write down the 3 above the line.
The final result is 68. Therefore, half of 136 is 68.
Discuss any potential challenges or common mistakes to avoid
While solving the equation, there are a few common mistakes that people often make. Let’s discuss them and learn how to avoid them:
Forgetting to bring down the next digit: It’s important to remember to bring down the next digit when performing long division. Forgetting to do so can lead to incorrect results.
Misplacing the decimal point: When dividing a decimal number, it’s crucial to place the decimal point in the correct position. Misplacing the decimal point can result in an inaccurate answer.
Not double-checking the calculation: It’s always a good practice to double-check your calculation to ensure accuracy. This can help catch any errors that might have occurred during the solving process.
To avoid these mistakes, take your time and carefully follow each step of the division process. If you’re unsure about any step, don’t hesitate to ask for help or consult a trusted resource.
