Why is this important? Percentages provide a standardized way to express parts of a whole. Understanding percentages is essential for making informed decisions in everyday life, from calculating discounts to analyzing financial data.
Our Analysis: To answer the question "What percent of 90 is 60?", we conducted a step-by-step analysis to break down the problem. We began by defining the relationship between the parts and the whole:
- Whole: 90
- Part: 60
- Percentage: The unknown value we need to find.
We used the formula "Percentage = (Part / Whole) * 100" to determine the percentage. This formula allows us to express the relationship between the part and the whole in a standardized percentage form.
Key Takeaways:
| Key Element | Description |
|---|---|
| Whole | The total value representing 100%. |
| Part | The specific value representing a portion of the whole. |
| Percentage | A standardized way to express the part in relation to the whole, expressed as a fraction of 100. |
The Calculation:
- Divide the part by the whole: 60 / 90 = 0.6667.
- Multiply the result by 100: 0.6667 * 100 = 66.67%.
Therefore, 60 is 66.67% of 90.
