Understanding Decimal Expansions

A decimal expansion is a way to represent a number using a base-10 system. Fractions can be expressed as decimals, which can either terminate (e.g., 1/4 = 0.25) or repeat (e.g., 1/3 = 0.333...).

Example: Converting a Fraction to a Decimal

To convert a fraction to a decimal, you perform long division. Divide the numerator by the denominator.

  • Numerator: The top number of a fraction (e.g., 1 in 1/17).
  • Denominator: The bottom number of a fraction (e.g., 17 in 1/17).

Dividing 1 by 17 results in the repeating decimal 0.0588235294117647...

Significance of Repeating Decimals

Repeating decimals represent rational numbers (numbers that can be expressed as a fraction p/q, where p and q are integers, and q is not zero). The decimal expansion of 1/17 is an example of a repeating decimal that represents a rational number.
