## Understanding Percentages

### Defining a Percentage

**A percentage is a way of expressing a fraction or a portion of a whole number.** It is often represented by the symbol “%”. In the case of money, percentages are commonly used to determine the proportion of a certain amount in relation to the total amount.

For example, if you have $100 and you want to calculate what percent of that is $25, you can use percentages to find the answer.

### Finding Percentages of Numbers

To find the percentage of a number, you can use a simple formula:

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

In the case of our example, we want to find out what percent of one US dollar is 25 cents. We can use the formula as follows:

**Percentage = (25 cents / 1 dollar) x 100**

Simplifying this equation, we get:

**Percentage = 25**

So, 25 cents is 25% of one US dollar.

It’s important to note that **percentages can be calculated for any amount**, not just money. **Whether you’re calculating the percentage of a discount, the percentage of a test score, or the percentage of a recipe ingredient, the formula remains the same.**

## Calculating 25% of 1 Dollar

### Setting Up the Calculation

When calculating 25% of 1 dollar, it’s important to understand that percentages represent a proportion or fraction of a whole. To begin, you need to set up the calculation correctly.

### Dividing 25 Cents by 1 Dollar

To determine what percent 25 cents is of 1 dollar, **you divide 25 cents by the value of 1 dollar.** In this case, **25 cents divided by 1 dollar equals 0.25.**

### Converting to a Percentage

**To convert the decimal value 0.25 to a percentage, you multiply it by 100. In this case, 0.25 multiplied by 100 equals 25%. Therefore, 25 cents is 25% of 1 dollar.**

It’s important to note that this calculation applies to the specific example given, and the percentage will vary depending on the values used. If you would like to calculate the percentage for different amounts, you can use the same formula.

Remember, dividing the smaller value by the larger value will result in a decimal, which can then be converted to a percentage.

## Using Fractions to Find 25% of 1 Dollar

### Writing 25 Cents as a Fraction

To find out what percent of one US dollar is 25 cents, **we can start by writing 25 cents as a fraction.** Since there are 100 cents in one dollar, **we can represent 25 cents as 25/100.** This fraction represents the ratio of 25 cents to one dollar.

### Simplifying the Fraction

To simplify the fraction 25/100, we can divide both the numerator and the denominator by their greatest common factor, which is 25. **Dividing 25 by 25 gives us 1, and dividing 100 by 25 gives us 4. Therefore, the simplified fraction is 1/4.**

**This means that 25 cents is equivalent to one-fourth of a dollar.**

### Converting the Fraction to a Percentage

To convert the fraction 1/4 into a percentage, we can multiply the fraction by 100. **Multiplying 1/4 by 100 gives us 25, so 1/4 is equivalent to 25%.** Therefore, 25 cents is 25% of one US dollar.

It’s important to note that fractions and percentages are different ways of expressing the same value.** Fractions represent a part-to-whole ratio, while percentages represent a part-to-whole comparison scaled to 100.** In this case, 25 cents is 25% of one dollar.

## Finding 25% of Other Dollar Amounts

### Using Proportions

Calculating 25% of any dollar amount can be done using proportions. **A proportion is a statement that two ratios are equal.** To find 25% of a dollar amount, you can set up a proportion with the known ratio of 25 cents to 1 dollar, and the unknown ratio of x cents to the dollar amount you want to find.

For example, if you want to** find 25% of $60,** you can set up the proportion:

**25 cents / 1 dollar = x cents / $60**

To solve for x, you can cross-multiply and divide:

**x = (25 cents * $60) / 1 dollar**

So, 25% of $60 is **equal to $15.**

### Applying the 25% Equivalence

Another way to find 25% of a dollar amount is by using the equivalence that 25% is the same as 0.25. To calculate, **you simply multiply the dollar amount by 0.25.**

For example, to find **25% of $80**, you can multiply:

**$80 * 0.25 = $20**

So, 25% of $80 is **equal to $20.**

It’s important to note that these methods can be applied to any dollar amount, not just whole numbers. Whether you’re looking to f**ind 25% of $5.75 or $125.50,** the same proportion or multiplication can be used to calculate the answer.
