Convert 12.25 to a Fraction: A Step-by-Step Guide
Fractions are essential in mathematics and everyday life. Understanding how to convert decimals to fractions is crucial, especially when dealing with numbers like 12.25. This article will provide a comprehensive guide to converting 12.25 into a fraction, exploring its significance and various applications.
Step 1: Multiply by 100
To convert a decimal to a fraction, we need to multiply it by a power of 10 that has the same number of digits as the decimal. In this case, we multiply 12.25 by 100.
| Decimal | Multiplication | Result |
|---|---|---|
| 12.25 | x 100 | 1225 |
Step 2: Create a Fraction
The result of the multiplication becomes the numerator of the fraction. The denominator is the power of 10 we used, which is 100 in this case.
| Numerator | Denominator | Fraction |
|---|---|---|
| 1225 | 100 | 1225/100 |
Step 3: Simplify the Fraction
The fraction 1225/100 can be simplified by dividing both the numerator and denominator by their greatest common factor (GCF), which is 25.
| Numerator | Denominator | Simplified Fraction |
|---|---|---|
| 1225 ÷ 25 | 100 ÷ 25 | 50 |
Therefore, 12.25 as a fraction is 50/100 or 1/2.
