Understanding the Problem: 24 3/4 ÷ 2

The core of the problem lies in understanding the nature of mixed numbers and how they interact with division. The number "24 3/4" is a mixed number, representing a whole number (24) and a fraction (3/4) combined. This means we have 24 complete units plus an additional three-quarters of a unit. Dividing this by 2 means we're splitting this entire quantity into two equal parts. This seemingly simple division problem allows for exploring several important mathematical concepts and strategies.

Method 1: Converting to an Improper Fraction

One efficient way to tackle this problem is by converting the mixed number into an improper fraction. An improper fraction has a numerator larger than its denominator. This conversion simplifies the division process.

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

To do this, we multiply the whole number (24) by the denominator (4) and add the numerator (3). This result becomes the new numerator, while the denominator remains the same.

24 x 4 + 3 = 99

Therefore, 24 3/4 is equal to 99/4.

Step 2: Perform the division.

Now we divide the improper fraction by 2. Dividing a fraction by a whole number is the same as multiplying the fraction by the reciprocal of the whole number. The reciprocal of 2 is 1/2.

(99/4) ÷ 2 = (99/4) x (1/2) = 99/8

Step 3: Simplify the result.

The resulting improper fraction, 99/8, can be converted back into a mixed number. We divide the numerator (99) by the denominator (8).

99 ÷ 8 = 12 with a remainder of 3

Therefore, 99/8 is equivalent to 12 3/8.

Conclusion of Method 1: By converting 24 3/4 to an improper fraction, we efficiently divided it by 2, resulting in 12 3/8.

Method 2: Dividing the Whole Number and Fraction Separately

This method involves dividing the whole number part and the fractional part separately and then combining the results. This approach is intuitively appealing and helps visualize the division process.

Step 1: Divide the whole number.

Divide the whole number 24 by 2:

24 ÷ 2 = 12

Step 2: Divide the fraction.

Divide the fraction 3/4 by 2:

(3/4) ÷ 2 = (3/4) x (1/2) = 3/8

Step 3: Combine the results.

Combine the results from steps 1 and 2:

12 + 3/8 = 12 3/8

Conclusion of Method 2: This method provides a clear, step-by-step approach, showcasing the division applied to both the whole number and fractional components independently, yielding the same result of 12 3/8.

Method 3: Decimal Conversion and Division

This method involves converting the mixed number into a decimal and then performing the division. This approach is particularly useful when dealing with calculations that require decimal precision.

Step 1: Convert the mixed number to a decimal.

To convert 24 3/4 to a decimal, we first convert the fraction 3/4 to a decimal. 3/4 = 0.75

Therefore, 24 3/4 = 24.75

Step 2: Perform the division.

Divide the decimal 24.75 by 2:

24.75 ÷ 2 = 12.375

Step 3: Convert the decimal back to a fraction (optional).

While 12.375 is a perfectly acceptable answer, we can convert it back to a fraction if needed. 0.375 is equivalent to 3/8. Therefore, 12.375 is equal to 12 3/8.

Conclusion of Method 3: This method demonstrates the flexibility of using decimal representations for calculations and showcases the equivalence between decimal and fractional representations.
