Understanding Fractions and Mixed Numbers

Before we dive into finding half of 23 3/4, let's clarify what fractions and mixed numbers are. A fraction represents a part of a whole, written as one number over another, such as 1/2 or 3/4. The top number is the numerator, and the bottom number is the denominator. A mixed number combines a whole number and a fraction, like 23 3/4, where 23 is the whole number and 3/4 is the fraction.

Fractions and mixed numbers are fundamental in mathematics and daily life. They help us describe portions, ratios, and divisions that aren't whole numbers. Understanding these concepts is essential for various applications, from cooking and baking to construction and finance.

To work with mixed numbers in calculations, it's often necessary to convert them into improper fractions. An improper fraction is one where the numerator is greater than or equal to the denominator, such as 7/2. Converting a mixed number to an improper fraction makes multiplication and division easier.

Converting a mixed number involves multiplying the whole number by the denominator of the fraction and adding the numerator. The result becomes the new numerator, while the denominator stays the same. For example, to convert 23 3/4 to an improper fraction:

• Multiply the whole number (23) by the denominator (4): 23 * 4 = 92
• Add the numerator (3) to the result: 92 + 3 = 95
• Place the result over the original denominator: 95/4

So, 23 3/4 is equivalent to 95/4 as an improper fraction. This conversion is a critical step in performing arithmetic operations, especially when finding half of a mixed number.

The concept of finding half of a number is essentially dividing it by 2. When dealing with fractions, dividing by 2 is the same as multiplying by 1/2. This simple trick can make the calculation straightforward, particularly when working with improper fractions. Understanding this equivalence is key to mastering fractional arithmetic.

Step-by-Step Calculation

Now, let’s get to the heart of the matter: finding half of 23 3/4. We'll break this down into manageable steps to ensure clarity and accuracy.

Step 1: Convert the mixed number to an improper fraction.

As we discussed earlier, converting 23 3/4 to an improper fraction involves multiplying the whole number (23) by the denominator (4) and adding the numerator (3). This gives us:

23 * 4 + 3 = 92 + 3 = 95

So, 23 3/4 is equivalent to 95/4.

Step 2: Multiply the improper fraction by 1/2.

To find half of 95/4, we multiply it by 1/2:

(95/4) * (1/2) = 95/8

Step 3: Simplify the resulting fraction.

The fraction 95/8 is an improper fraction, which means the numerator is greater than the denominator. To make it easier to understand, we convert it back to a mixed number. We divide 95 by 8:

95 ÷ 8 = 11 with a remainder of 7

This means that 95/8 is equal to 11 whole units and 7/8 of another unit. Therefore, the mixed number is 11 7/8.

Step 4: Present the final answer.

So, half of 23 3/4 is 11 7/8.

This step-by-step approach simplifies the process, making it easy to follow and understand. By breaking down the problem into smaller, manageable steps, you can confidently find half of any mixed number. Remember, the key is to convert to an improper fraction, multiply by 1/2, and then simplify back to a mixed number if needed.

Understanding each of these steps allows you to tackle similar problems with ease. The conversion to an improper fraction ensures accurate multiplication, while simplifying back to a mixed number provides a more intuitive understanding of the quantity. This method is not only mathematically sound but also practical for real-world applications.
