- Identify the number for which the percentage is required (20).
- Identify the percentage to be calculated (80%).
- Express the percentage as a decimal by dividing it by 100. So, 80% becomes 80/100 = 0.8.
- Calculate the required percentage by multiplying the decimal form of the percentage (0.8) with the given number (20).
- Determine the result of the multiplication to find the required percentage of the given number.
Calculation Example
To illustrate the calculation process, let's apply the steps outlined above. The given number is 20, and we need to find 80% of it. Here's the step-by-step calculation:
| Step | Description | Calculation |
|---|---|---|
| 1 | Identify the number | 20 |
| 2 | Express the percentage as a decimal | 80/100 = 0.8 |
| 3 | Calculate 80% of 20 | 20 × 0.8 = 16 |
Interpreting the Result
After performing the calculation, we find that 80% of 20 is equal to 16. This means that 16 is 80% of the given number 20. It's essential to understand the context and relevance of the calculation to interpret the result accurately.
