Calculating 12 1/2 percent of 92 can be done using a variety of methods, each offering a unique perspective on the underlying mathematics. Whether you're using traditional arithmetic or leveraging modern technologies like AI-driven math apps, there are several approaches to solve this problem efficiently.
Method 1: Converting to a Decimal and Multiplying
To find 12 1/2 percent of 92, we first convert 12 1/2 to a decimal. 12 1/2 can be written as 12.5, and 12.5 percent is 0.125. We then multiply this decimal by 92:
0.125 x 92 11.5
Method 2: Using Fractions
Another approach involves using fractions. Since 12 1/2 is equivalent to 25/2, we can write:
(25/2) x (92/100) 2300/200 11.5
Alternatively, we can use the fact that 12 1/2 is the same as 1/8:
92/8 11.5
Method 3: Simplified Multiplication
For a quicker calculation, you can make 92 into 9200 and multiply it by 125. Then, divide the result by 1000 to normalize the number back to its original scale:
9200 x 125 1150000
1150000 / 1000 1150
However, for 12 1/2 of 92 specifically, this method is not as straightforward, and the direct fraction method or decimal conversion would be more appropriate.
Step-by-Step Explanation with Alternative Methods
Consider another way to find 12 1/2 of 92. First, convert 12 1/2 to 12.5, and then consider it as 12.5/100, which simplifies to 0.125. We can split the calculation into two steps to break it down further:
Step 1: Calculate 12 of 92, which is 12 x 92 / 100 10.92 (approximately 11).
Step 2: Calculate 0.5 of 92, which is 92 x 0.5 / 100 0.5 (approximately 0.5).
Total: Add the two results: 11 0.5 11.5
Conclusion
Regardless of the method used, the final answer for 12 1/2 percent of 92 is 11.5. Utilizing a combination of fractions, decimals, or different step-by-step breakdowns can enhance your understanding of the problem and provide flexibility in solving similar calculations.
