The denominator of a repeating decimal is often 99 because it represents the fraction of the repeating part of the decimal. For example, if you have a repeating decimal like 0.33..., the repeating part "33" has two digits, leading to a denominator of 99 (i.e., 33/99). This is derived from the fact that multiplying the repeating decimal by a power of 10 equal to the number of digits in the repeat allows you to set up an equation that results in 99 as the denominator when solved.

When you write a repeating decimal into a fraction why does the fraction always have only 9s or 9s and 0s as digits in the denominator?
When converting a repeating decimal into a fraction, the reason the denominator consists of 9s or a combination of 9s and 0s is rooted in the nature of the decimal system. Each digit in the repeating part corresponds to a division by powers of 10, while the repeating cycle creates a geometric series. The formula for converting a repeating decimal to a fraction effectively captures this series, resulting in a denominator that is a series of 9s for each repeating digit, and 0s for any non-repeating digits that precede the repeating section. For example, in the decimal 0.666..., the repeating '6' creates a fraction with a denominator of 9, while a decimal like 0.1(23) would result in a denominator of 990, reflecting both the repeating and non-repeating parts.
