Fraction $\frac{-2}{9}$ can be rewritten as $-\frac{2}{9}$ by extracting the negative sign.
$$sort(\frac{2}{3},-\frac{2}{9},\frac{-5}{3})$$
Fraction $\frac{-5}{3}$ can be rewritten as $-\frac{5}{3}$ by extracting the negative sign.
$$sort(\frac{2}{3},-\frac{2}{9},-\frac{5}{3})$$
Least common denominator of the numbers in the list $\frac{2}{3},-\frac{2}{9},-\frac{5}{3}$ is $9$. Convert numbers in the list to fractions with denominator $9$.
$$\frac{6}{9},-\frac{2}{9},-\frac{15}{9}$$
To sort the list, start from a single element $\frac{6}{9}$.
$$\frac{6}{9}$$
Insert $-\frac{2}{9}$ to the appropriate location in the new list.
$$-\frac{2}{9},\frac{6}{9}$$
Insert $-\frac{15}{9}$ to the appropriate location in the new list.
$$-\frac{15}{9},-\frac{2}{9},\frac{6}{9}$$
Replace the obtained fractions with the initial values.
