# Decimal Fraction

## Decimal Fraction

Fraction or fractional expression that can be expressed with a denominator that is a power of 10.

### Property

All decimal fractions express a decimal number and all decimal numbers can be expressed as a decimal fraction.

### Examples

The fractions $$\frac{3}{10}, \frac{17}{100}, \frac{27}{1000}$$ and $$\frac{83}{1\space 000\space 000}$$are decimal fractions.

The fractions $$\frac{3}{4},\frac{4}{5}, \frac{3}{20}$$ and $$\frac{17}{25}$$ might not seem like they are decimal fractions, because their denominators are not powers of 10. However, we can find an equivalent fraction where the denominator is a power of 10.
Therefore, we find $$\frac{75}{100},\frac{8}{10}, \frac{15}{100}$$ and $$\frac{68}{100}$$.
