Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=2$, $b=3$, $c=\pi $, $a/b=\frac{2}{3}$ e $ca/b=\pi \left(\frac{2}{3}\right)$

Applicare la formula: $\frac{\frac{a}{b}}{c}$$=\frac{a}{bc}$, dove $a=\pi \cdot 2$, $b=3$, $c=3$, $a/b/c=\frac{\frac{\pi \cdot 2}{3}}{3}$ e $a/b=\frac{\pi \cdot 2}{3}$
