$$$$

Introduction

In mathematics, percentages are a way to express a value as a fraction of $100$. To find the percentage of a given value, we need to divide the value by the total and multiply by $100$. In this article, we will explore how to find the percentage of a given value, using the example of finding what percent of $1.8$ is $40$.

Understanding Percentages

Percentages are a way to express a value as a fraction of $100$. For example, if we have a value of $25$ and we want to express it as a percentage of $100$, we can divide $25$ by $100$ and multiply by $100$ to get $25\%$. This means that $25$ is $25\%$ of $100$.

Finding the Percentage

To find the percentage of a given value, we need to divide the value by the total and multiply by $100$. In this case, we want to find what percent of $1.8$ is $40$. To do this, we can divide $40$ by $1.8$ and multiply by $100$.

Calculating the Percentage

Let's calculate the percentage:

$$\frac{40}{1.8} \times 100 = \frac{4000}{1.8} = 2222.22\%$$

Understanding the Result

The result of the calculation is $2222.22\%$. This means that $40$ is $2222.22\%$ of $1.8$.

Conclusion

In conclusion, to find the percentage of a given value, we need to divide the value by the total and multiply by $100$. Using the example of finding what percent of $1.8$ is $40$, we calculated the percentage to be $2222.22\%$. This means that $40$ is $2222.22\%$ of $1.8$.

Q&A

Q: What is a percentage?

A: A percentage is a way to express a value as a fraction of $100$. For example, if we have a value of $25$ and we want to express it as a percentage of $100$, we can divide $25$ by $100$ and multiply by $100$ to get $25\%$. This means that $25$ is $25\%$ of $100$.

Q: How do I calculate a percentage?

A: To calculate a percentage, you need to divide the value by the total and multiply by $100$. For example, if you want to find what percent of $1.8$ is $40$, you can divide $40$ by $1.8$ and multiply by $100$.

Q: What is the formula for finding a percentage?

A: The formula for finding a percentage is:

$$\frac{value}{total} \times 100$$

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

A: A percentage is a way to express a value as a fraction of $100$, while a ratio is a way to express a value as a fraction of another value. For example, if we have a value of $25$ and we want to express it as a percentage of $100$, we can divide $25$ by $100$ and multiply by $100$ to get $25\%$. If we want to express $25$ as a ratio of $100$, we can write it as $25:100$.

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

A: To convert a percentage to a decimal, you need to divide the percentage by $100$. For example, if you have a percentage of $25\%$, you can convert it to a decimal by dividing $25$ by $100$ to get $0.25$.

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

A: To convert a decimal to a percentage, you need to multiply the decimal by $100$. For example, if you have a decimal of $0.25$, you can convert it to a percentage by multiplying $0.25$ by $100$ to get $25\%$.
