To convert the decimal .325 into a fraction, we will break down the process step-by-step, ensuring clarity and simplicity. Understanding how to change decimal numbers into fractions is an essential skill in mathematics, which can also help in various real-life situations. Let’s dive into the conversion process!
Understanding Decimals and Fractions
Before we proceed with the conversion, it’s crucial to understand what decimals and fractions are.
Decimals are numbers expressed in the base-10 number system, which is the standard numerical system we use daily. They can represent whole numbers and parts of a whole, with the decimal point separating these two components.
Fractions, on the other hand, represent parts of a whole using two numbers: the numerator (the top part) and the denominator (the bottom part). For example, in the fraction ( \frac{1}{2} ), 1 is the numerator, and 2 is the denominator, indicating that one part out of two equal parts is being considered.
Step-by-Step Conversion of .325 to a Fraction
Step 1: Write the Decimal as a Fraction
Start by writing .325 as a fraction with a denominator of 1:
[ .325 = \frac{.325}{1} ]
Step 2: Eliminate the Decimal
To eliminate the decimal point, we multiply both the numerator and the denominator by 1000 (because there are three digits after the decimal):
[ .325 \times 1000 = 325 ]
So, we have:
[ .325 = \frac{325}{1000} ]
Step 3: Simplify the Fraction
Next, we need to simplify ( \frac{325}{1000} ). This involves finding the greatest common divisor (GCD) of 325 and 1000.
Finding the GCD:
- The factors of 325 are: 1, 5, 25, 13, 65, 325
- The factors of 1000 are: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, 1000
The greatest common divisor is 25.
Now, divide both the numerator and the denominator by the GCD (25):
[ \frac{325 \div 25}{1000 \div 25} = \frac{13}{40} ]
Final Result
Thus, the decimal .325 converts to the fraction ( \frac{13}{40} ).
