In this article, we will explore the value of 1/2 of 800 and present several methods to arrive at this solution. Whether you are a student, a professional, or simply curious about mathematical operations, this guide aims to provide clarity and insight into solving similar problems.

Method 1: Conversion to Decimal and Multiplication

One straightforward method to find 1/2 of 800 is to first convert the fraction to a decimal and then multiply it by the given number. Here's how:

Convert 1/2 to a decimal. Multiply the resulting decimal by 800.

Let's go through each step in detail:

Step 1: Convert 1/2 to a Decimal

The fraction 1/2 can be expressed as a decimal by performing the division:

1/2 1 ÷ 2 0.5

Alternatively, you can represent it as:

1/2 1/2 × 100/100 100/200 0.5

This shows that 1/2 is equivalent to 0.5 in decimal form.

Step 2: Multiply the Decimal by 800

Now, multiply the decimal by 800 to find the value:

0.5 × 800 400 ÷ 2 4

Therefore, 1/2 of 800 is 400 divided by 2, which equals 4.

Method 2: Direct Multiplication

Another method to find 1/2 of 800 involves a more direct approach:

1/2 of 800 0.5 × 800 400 ÷ 2 4

This method simplifies the calculation by recognizing that multiplying a number by 0.5 is equivalent to dividing it by 2.

Method 3: Multiplication and Fraction Representation

Let's explore a third method involving multiplication and fraction representation:

Express 1/2 of 800 using the rule p of q q of p. Recognize that 800 represents 8 times the actual value. Substitute and simplify to find the result.

Here's how it works:

1/2 of 800 800 of 1/2

800 of 1/2 800 ÷ 2 400 ÷ 2 4

This method effectively breaks down the problem into simpler, more manageable parts.

Another Example: 0.5 of 800

It's also useful to understand related problems, such as finding 0.5 of 800. This is equivalent to finding 1/2 of 800, as explained earlier. Here's the breakdown:

0.5 of 800 800 of 0.5 800 ÷ 2 400 ÷ 2 4

Thus, 0.5 of 800 is 4.

Conclusion:

In summary, finding 1/2 of 800 can be achieved through various methods, including conversion to decimals, direct multiplication, and fraction representation. Each method provides a different perspective on the problem and can be applied depending on the context or the solver's preference.
