Learn how to express 2.25 as a fraction and its different forms. Explore real-world applications of fractions in this comprehensive guide.

## Introduction

Fractions are a fundamental concept in mathematics, and they are used daily in our lives. They represent a part of a whole and are commonly expressed as a ratio of two numbers. In this article, we will explore the fraction of 2.25 and how to express it in various forms.

## Understanding Fractions

Before we dive into the fraction of 2.25, we need to understand the basics of fractions. A fraction has two parts: the numerator and the denominator. The numerator represents the number of parts we have, while the denominator represents the total number of parts in the whole.

For example, let’s consider the fraction 3/4. Here, the numerator is 3, which means we have three parts, and the denominator is 4, which represents the total number of parts in the whole.

Fractions can be expressed in different forms, such as proper fractions, improper fractions, and mixed fractions. In a proper fraction, the numerator is less than the denominator, while in an improper fraction, the numerator is greater than or equal to the denominator. In a mixed fraction, we have a whole number and a fraction combined.

## Expressing 2.25 as a Fraction

Now, let’s look at how to express 2.25 as a fraction. 2.25 is a decimal, and we can convert it to a fraction by placing the decimal over a power of 10. Since we have two digits after the decimal, we can place it over 100.

So, 2.25 can be written as 225/100. However, this fraction can be simplified by dividing both the numerator and denominator by the greatest common factor, which is 25.

Therefore, the fraction of 2.25 can be expressed as 9/4, which is an improper fraction. We can also express it as a mixed fraction, which would be 2 1/4.

Knowing how to express 2.25 as a fraction is useful in many areas, such as when dealing with money or measurements. In the next section, we will explore some real-world applications of fractions.

## Conclusion

## Converting Fractions to Decimals

In addition to converting decimals to fractions, we can also convert fractions to decimals. To do this, we simply divide the numerator by the denominator. Let’s use the fraction 9/4 as an example.

When we divide 9 by 4, we get 2 with a remainder of 1. To convert the remainder to a decimal, we need to add a decimal point and a zero to the end of the dividend and continue dividing.

So, 1 becomes 10, and when we divide 10 by 4, we get 2 with a remainder of 2. We continue this process until we reach the desired level of accuracy.

In this case, we can stop after one decimal place, giving us 2.25, which is the original decimal we started with. This shows that fractions and decimals are equivalent representations of the same value.

## Simplifying Fractions

In the previous section, we saw how to simplify a fraction by dividing both the numerator and denominator by the greatest common factor. Simplifying fractions is important because it makes them easier to work with in calculations and comparisons.

For example, imagine we have two fractions, 2/5 and 4/10. These fractions represent the same value, but 2/5 is already in its simplest form, while 4/10 can be simplified by dividing both the numerator and denominator by 2.

After simplification, we get 2/5, which is the same as the original fraction. Knowing how to simplify fractions is essential in many areas of math, such as algebra, where we often need to manipulate fractions to solve equations.

## Conclusion

In conclusion, fractions are a vital part of mathematics and have many real-world applications. Understanding how to express decimals as fractions and vice versa, convert fractions to decimals, and simplify fractions are crucial skills in many areas of math and daily life. By mastering these concepts, we can develop a deeper understanding of fractions and use them effectively in problem-solving and decision-making.

## Comparing Fractions

When working with fractions, we often need to compare them to determine which one is greater or less than the other. To compare fractions, we can use a common denominator, which means we convert both fractions to have the same denominator.

For example, let’s compare 3/4 and 5/8. To do this, we need to find a common denominator, which in this case would be 8. We can convert 3/4 to 6/8 by multiplying both the numerator and denominator by 2. Similarly, we can convert 5/8 to 5/8 since it already has the same denominator.

Now that both fractions have the same denominator, we can compare the numerators. In this case, 6/8 is greater than 5/8, so 3/4 is greater than 5/8.

## Conclusion

In conclusion, fractions are an essential concept in mathematics that we encounter in our daily lives. In this article, we explored the fraction of 2.25 and how it can be expressed in various forms. We also looked at some real-world applications of fractions and how to compare them. By understanding fractions, we can make sense of the world around us and solve problems more effectively.
