Introduction

In mathematics, percentages and fractions are two ways to express a part of a whole. While they may seem like different concepts, they can be equivalent in certain situations. In this article, we will explore the relationship between percentages and fractions, and determine which sign makes the statement true: $50\%$ or $\frac{37}{100}$ .

Understanding Percentages

A percentage is a way to express a value as a fraction of 100. It is denoted by a percent sign (%) and is often used to express a proportion or a rate. For example, $50\%$ means 50 out of 100, or $\frac{50}{100}$ . Percentages can be used to express a wide range of values, from simple proportions to complex rates.

Understanding Fractions

A fraction is a way to express a part of a whole. It consists of two parts: a numerator and a denominator. The numerator represents the number of equal parts, and the denominator represents the total number of parts. For example, $\frac{37}{100}$ means 37 out of 100. Fractions can be used to express a wide range of values, from simple proportions to complex rates.

Converting Percentages to Fractions

To convert a percentage to a fraction, we can use the following formula:

\text{Percentage} = \frac{\text{Number}}{100}

For example, to convert $50\%$ to a fraction, we can use the following formula:

50\% = \frac{50}{100}

This simplifies to $\frac{1}{2}$ .

Converting Fractions to Percentages

To convert a fraction to a percentage, we can use the following formula:

\text{Percentage} = \frac{\text{Numerator}}{\text{Denominator}} \times 100

For example, to convert $\frac{37}{100}$ to a percentage, we can use the following formula:

\frac{37}{100} = \frac{37}{100} \times 100 = 37\%

Comparing Percentages and Fractions

Now that we have converted both $50\%$ and $\frac{37}{100}$ to equivalent fractions, we can compare them. We have found that $50\%$ is equivalent to $\frac{1}{2}$ , and $\frac{37}{100}$ is equivalent to $37\%$ . Since $\frac{1}{2}$ is not equal to $37\%$ , we can conclude that the two signs do not make the statement true.

Conclusion

In conclusion, while percentages and fractions may seem like different concepts, they can be equivalent in certain situations. By converting $50\%$ and $\frac{37}{100}$ to equivalent fractions, we have found that they are not equal. Therefore, we can conclude that the statement is not true for either sign.

Percentages and fractions are two ways to express a part of a whole. While they may seem like different concepts, they can be equivalent in certain situations. In this article, we will answer some frequently asked questions about percentages and fractions, and provide additional resources for further learning.

Q&A

Q: What is the difference between a percentage and a fraction?

A: A percentage is a way to express a value as a fraction of 100, while a fraction is a way to express a part of a whole. For example, $50\%$ means 50 out of 100, or $\frac{50}{100}$ . Fractions can be used to express a wide range of values, from simple proportions to complex rates.

Q: How do I convert a percentage to a fraction?

A: To convert a percentage to a fraction, you can use the following formula:

\text{Percentage} = \frac{\text{Number}}{100}

For example, to convert $50\%$ to a fraction, we can use the following formula:

50\% = \frac{50}{100}

This simplifies to $\frac{1}{2}$ .

Q: How do I convert a fraction to a percentage?

A: To convert a fraction to a percentage, you can use the following formula:

\text{Percentage} = \frac{\text{Numerator}}{\text{Denominator}} \times 100

For example, to convert $\frac{37}{100}$ to a percentage, we can use the following formula:

\frac{37}{100} = \frac{37}{100} \times 100 = 37\%

Q: What is the relationship between percentages and decimals?

A: Percentages and decimals are related, but not the same thing. A percentage is a way to express a value as a fraction of 100, while a decimal is a way to express a value as a fraction with a denominator of 10. For example, $50\%$ is equivalent to $0.5$ , while $\frac{37}{100}$ is equivalent to $0.37$ .

Q: How do I add and subtract percentages?

A: To add and subtract percentages, you can use the following formulas:

\text{Percentage 1} + \text{Percentage 2} = \frac{\text{Numerator 1}}{\text{Denominator 1}} + \frac{\text{Numerator 2}}{\text{Denominator 2}}

\text{Percentage 1} - \text{Percentage 2} = \frac{\text{Numerator 1}}{\text{Denominator 1}} - \frac{\text{Numerator 2}}{\text{Denominator 2}}

For example, to add $50\%$ and $25\%$ , we can use the following formula:

50\% + 25\% = \frac{50}{100} + \frac{25}{100} = \frac{75}{100} = 75\%

Q: How do I multiply and divide percentages?

A: To multiply and divide percentages, you can use the following formulas:

\text{Percentage 1} \times \text{Percentage 2} = \frac{\text{Numerator 1}}{\text{Denominator 1}} \times \frac{\text{Numerator 2}}{\text{Denominator 2}}

\text{Percentage 1} \div \text{Percentage 2} = \frac{\text{Numerator 1}}{\text{Denominator 1}} \div \frac{\text{Numerator 2}}{\text{Denominator 2}}

For example, to multiply $50\%$ and $25\%$ , we can use the following formula:

50\% \times 25\% = \frac{50}{100} \times \frac{25}{100} = \frac{1250}{10000} = 12.5\%
