Step-by-Step Guide to Convert 12⁄25 to a Percentage
Let’s break down the process of converting 12⁄25 into a percentage. Follow these steps for clarity and accuracy:
- Step 1: Divide the numerator by the denominator
- Step 2: Multiply the result by 100
- Step 3: Write the final answer
First, we need to divide the numerator (the top number) of the fraction by the denominator (the bottom number). In our case, we divide 12 by 25.
| Calculation | Result |
|---|---|
| 12 ÷ 25 | 0.48 |
Next, take the result of the division and multiply it by 100 to convert it into a percentage.
| Calculation | Result |
|---|---|
| 0.48 × 100 | 48 |
The final step is to add the percentage symbol to the result. Therefore, 12/25 as a percentage is 48%.
Practical Application: Real-World Examples
To understand how this conversion applies in real life, let’s look at a few practical examples:
- Example 1: Grading
- Example 2: Budgeting
- Example 3: Statistics
Imagine you’ve scored 12 out of 25 in a test. To find out your percentage score, you convert the fraction 12/25 to a percentage. Following the steps above, you get 48%. This means you answered 48% of the questions correctly.
Suppose you have a budget of $25 and you spend $12. To see what percentage of your budget you’ve used, convert 12/25 to a percentage. You’ll find that 48% of your budget was spent, providing a clear view of your spending.
In a survey where 12 out of 25 respondents favor a particular policy, to find the percentage of supporters, you convert 12/25 to a percentage. Again, you determine that 48% of respondents support the policy.
