**Calculating Percentage: What Percent of 60 is 21?**

Do you often wonder about the mathematical relationships between numbers? One common question that arises is determining the percentage of one number in relation to another. In this blog post, we will delve into the calculation of what percent of 60 is 21. Understanding percentages is a fundamental skill with practical applications in various fields, including finance, statistics, and everyday life.

**The Need for Percentage Calculation:**

Whether it’s determining the discount on a purchase or calculating the proportion of a survey sample, percentages provide us with a concise and clear way to express numerical relationships. Understanding percentages allows us to compare numbers of different magnitudes, draw meaningful conclusions, and make informed decisions.

**What Percent of 60 is 21?**

To calculate what percent of 60 is 21, we use the formula:

Percentage = (Part / Whole) * 100

Substituting the given values:

Percentage = (21 / 60) * 100

= 0.35 * 100

= 35%

**Summary:**

In this article, we explored the concept of what percent of 60 is 21. We emphasized the importance of understanding percentages in various practical applications, such as finance, statistics, and everyday life. By applying the formula Percentage = (Part / Whole) * 100, we determined that 21 is 35% of 60. This understanding enables us to compare, quantify, and make sense of numerical relationships more effectively.

## What Percent of 60 is 21?

The question “what percent of 60 is 21?” can be solved using the formula:

```
(Part / Whole) x 100 = Percentage
```

In this case, the part is 21 and the whole is 60.

```
(21 / 60) x 100 = 35
```

Therefore, 21 is 35% of 60.

## Determining Percentage

To determine the percentage that one number represents of another, follow these steps:

- Divide the part by the whole.
- Multiply the result by 100.

For example, to find what percent 15 is of 50:

```
(15 / 50) x 100 = 30%
```

Therefore, 15 is 30% of 50.

## Applications of Percentages

Percentages have various applications in daily life and different fields, such as:

**Finance:**Calculating interest rates, discounts, and tax amounts.**Measurements:**Expressing proportions and comparing quantities.**Science:**Determining concentrations, ratios, and probabilities.**Business:**Analyzing market share, sales growth, and financial performance.

## Converting Fractions to Percentages

To convert a fraction to a percentage, divide the numerator by the denominator and multiply by 100.

For example, to convert 3/5 to a percentage:

```
(3 / 5) x 100 = 60%
```

Therefore, 3/5 is equal to 60%.

## Converting Decimals to Percentages

To convert a decimal to a percentage, multiply it by 100.

For example, to convert 0.75 to a percentage:

```
0.75 x 100 = 75%
```

Therefore, 0.75 is equal to 75%.

## Solving Percent Problems

To solve percent problems, use the following formulas:

### Finding the Part

```
Part = Percentage / 100 x Whole
```

### Finding the Whole

```
Whole = Part / Percentage x 100
```

### Finding the Percentage

```
Percentage = Part / Whole x 100
```

## Real-World Examples of Percentages

Percentages are used in numerous real-world situations:

**Sales tax:**A sales tax of 8% means that for every $100 spent, you pay an additional $8 in tax.**Discounts:**A discount of 20% means that the price of an item is reduced by 20%.**Interest rates:**A bank offers an interest rate of 5% per year on savings accounts.**Election results:**In an election, a candidate received 60% of the votes.

## Conclusion

Understanding percentages is essential for navigating various aspects of life and making informed decisions. By applying the concepts and formulas discussed in this article, you can effectively calculate and interpret percentages in different contexts.

## Frequently Asked Questions (FAQs)
