Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=27$, $b=2$, $c=\frac{3}{2}$, $a/b=\frac{27}{2}$ e $ca/b=1.5\cdot \left(\frac{27}{2}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=1.5\cdot 27$, $a=\frac{3}{2}$ e $b=27$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=\frac{81}{2}$, $b=2$ e $a/b=\frac{40.5}{2}$
