Understanding Decimal to Fraction Conversion

Converting a decimal to a fraction involves expressing the decimal value as a ratio of two integers (a numerator and a denominator). The process is straightforward and relies on understanding place value.

Converting 0.165 to a Fraction

1. Write the decimal as a fraction with a denominator of 1:

   0.165/1

2. Multiply the numerator and denominator by a power of 10 to remove the decimal point: Since there are three digits after the decimal point, we multiply by 1000 (10³).

   (0.165 * 1000) / (1 * 1000) = 165/1000

3. Simplify the fraction: Now we need to find the greatest common divisor (GCD) of 165 and 1000 to simplify the fraction to its lowest terms.

   • Finding the GCD: The GCD of 165 and 1000 is 5. You can find this using prime factorization or the Euclidean algorithm.

4. Divide both the numerator and denominator by the GCD:

   165 ÷ 5 = 33 1000 ÷ 5 = 200

Therefore, the simplified fraction is 33/200.

Why is Simplifying Important?

Simplifying a fraction reduces it to its simplest form, making it easier to understand and work with. 33/200 is much easier to grasp than 165/1000.

Practical Applications

Understanding decimal-to-fraction conversion is crucial in various fields:

• Baking and Cooking: Recipes often use fractions for precise measurements.
• Engineering and Construction: Accurate measurements are essential for precision work.
• Finance: Calculations involving percentages and interest rates frequently involve fractions.
• Mathematics: A fundamental skill in arithmetic and algebra.

FAQs about Decimal to Fraction Conversion

• Q: What if the decimal is a repeating decimal? A: Converting repeating decimals to fractions requires a slightly different approach involving setting up an equation and solving for x.

• Q: Can I use a calculator to simplify fractions? A: Yes, many calculators have a "simplify fraction" function.

This guide showed you how to convert 0.165 to a fraction. Remember the steps: write it as a fraction over 1, multiply to remove the decimal, and then simplify by finding the greatest common divisor. This method can be applied to converting any decimal to a fraction.
