Understanding decimals and fractions is a fundamental skill in mathematics. This article will guide you through the simple process of converting the decimal 0.004 into its fractional equivalent. We'll break it down step-by-step, making it easy for everyone to understand.

Understanding Decimals and Fractions

Before we begin the conversion, let's quickly review the relationship between decimals and fractions. Decimals represent parts of a whole using a base-ten system (tenths, hundredths, thousandths, etc.). Fractions also represent parts of a whole, but express them as a ratio of two numbers (numerator over denominator).

Converting 0.004 to a Fraction: The Process

Here's how to convert 0.004 to a fraction:

Identify the place value: The last digit of 0.004 is in the thousandths place. This tells us our denominator will be 1000.
Write the numerator: The digits of the decimal become the numerator of the fraction. In this case, the numerator is 4.
Form the fraction: Putting the numerator and denominator together, we get the fraction 4/1000.

Therefore, 0.004 as a fraction is $\frac{4}{1000}$ .

Simplifying the Fraction

While 4/1000 is a correct representation, fractions are often simplified to their lowest terms. To simplify, we need to find the greatest common divisor (GCD) of the numerator and denominator. The GCD of 4 and 1000 is 4.

Dividing both the numerator and denominator by 4, we get:

$\frac{4}{1000} = \frac{4 \div 4}{1000 \div 4} = \frac{1}{250}$

0.004 as a Fraction: The Simplified Answer

Therefore, the simplest form of 0.004 as a fraction is $\boxed{1/250}$ .

Frequently Asked Questions (FAQs)

Q: How do I convert other decimals to fractions?

A: Follow the same steps outlined above. Identify the place value of the last digit to determine the denominator. The digits of the decimal form the numerator. Then, simplify the fraction to its lowest terms by dividing both numerator and denominator by their GCD.

Q: What if the decimal has a whole number part?

A: If the decimal has a whole number part (e.g., 2.004), convert the decimal part to a fraction as shown above (1/250). Then, add the whole number. 2.004 would become 2 + 1/250 or you could express this as an improper fraction: (500+1)/250 = 501/250

Conclusion

Converting decimals to fractions is a straightforward process that involves understanding place value and simplifying fractions. Now you know how to convert 0.004 to the fraction 1/250. Remember to always simplify your fraction to its lowest terms for the most concise representation. Mastering this skill will strengthen your foundational understanding of mathematics.
