## Useful for Fractions

\frac{3}{5}

When we simplify a fraction as much as possible, then the top and bottom numbers (the numerator and denominator) are **coprime**.

\frac{6}{10} = \frac{3}{5}

If the top and bottom numbers of a fraction are **not coprime** (like 6 and 10 that share the factor 2), then we can simplify the fraction.
