Simplifying fractions is a fundamental concept in mathematics, and it's essential to master this skill to tackle more complex mathematical problems. The fraction 2.25 can be simplified in a few easy steps, making it easier to work with in various mathematical operations. In this article, we'll explore three easy ways to simplify 2.25 as a fraction.
Why Simplify Fractions?
Simplifying fractions helps to reduce the complexity of mathematical expressions, making it easier to perform calculations and understand the underlying concepts. Simplified fractions also facilitate comparison and ordering of fractions, which is crucial in various mathematical applications.
Method 1: Convert the Decimal to a Fraction
To simplify 2.25 as a fraction, we can start by converting the decimal to a fraction. We can write 2.25 as 2 + 0.25. The decimal part, 0.25, can be converted to a fraction by dividing it by 1.
0.25 = 25/100
Now, we can simplify the fraction 25/100 by dividing both the numerator and the denominator by 25.
25 ÷ 25 = 1 100 ÷ 25 = 4
So, 0.25 can be simplified to 1/4. Therefore, 2.25 can be written as:
2 + 1/4 = 2 1/4
Step-by-Step Solution:
- Write 2.25 as 2 + 0.25
- Convert 0.25 to a fraction: 25/100
- Simplify the fraction: 1/4
- Combine the whole number and the fraction: 2 1/4
Method 2: Use the Place Value System
Another way to simplify 2.25 as a fraction is to use the place value system. We can write 2.25 as 225/100, where the decimal part is shifted two places to the left.
225/100 can be simplified by dividing both the numerator and the denominator by 25.
225 ÷ 25 = 9 100 ÷ 25 = 4
So, 225/100 can be simplified to 9/4.
Step-by-Step Solution:
- Write 2.25 as 225/100
- Simplify the fraction: 9/4
- Write the fraction in mixed form: 2 1/4
Method 3: Use a Calculator or Online Tool
In today's digital age, we have access to calculators and online tools that can simplify fractions in a matter of seconds. You can use a calculator or an online fraction simplifier tool to simplify 2.25 as a fraction.
For example, if you enter 2.25 into an online fraction simplifier tool, it will output the simplified fraction 9/4.
Step-by-Step Solution:
- Enter 2.25 into a calculator or online fraction simplifier tool
- Get the simplified fraction: 9/4
- Write the fraction in mixed form: 2 1/4
Conclusion
Simplifying 2.25 as a fraction is a straightforward process that can be done using various methods. Whether you use the decimal-to-fraction conversion method, the place value system, or a calculator or online tool, the result is the same: 2.25 can be simplified to 9/4 or written in mixed form as 2 1/4.
