Understanding percentages is a fundamental skill in everyday life. From calculating discounts at the store to analyzing financial data, percentages play a crucial role in making informed decisions. One common scenario where we encounter percentages is when determining what proportion one number represents of another. For example, “26 is what percent of 65?” This seemingly simple question unlocks a deeper understanding of how percentages work and their practical applications.
This blog post will delve into the concept of percentages, explore the calculation of “26 is what percent of 65?”, and highlight the significance of this calculation in various real-world contexts. We’ll break down the process step-by-step, providing clear explanations and illustrative examples to solidify your understanding.
Understanding Percentages
A percentage is a fraction expressed out of one hundred. The symbol “%” represents “out of one hundred.” For instance, 50% means 50 out of every 100, which can be written as the fraction 50/100 or the decimal 0.50. Percentages are widely used to express proportions, ratios, and changes in quantities.
Calculating Percentages
To calculate a percentage, follow these steps:
- Divide the part by the whole.
- Multiply the result by 100.
For example, if you want to find 20% of 100, you would: (See Also: Algebra Problem How Middle School Math? Mastering The Basics)
- Divide 20 by 100: 20 / 100 = 0.20
- Multiply the result by 100: 0.20 * 100 = 20%
Calculating “26 Is What Percent of 65?”
Now, let’s apply this knowledge to our specific question: “26 is what percent of 65?”
Step-by-Step Calculation
- **Divide the part (26) by the whole (65):** 26 / 65 = 0.40
- **Multiply the result by 100 to express it as a percentage:** 0.40 * 100 = 40%
Therefore, 26 is 40% of 65.
