Applicare la formula: $ab$$=ab$, dove $ab=16\cdot 4\cdot \left(\frac{1}{2}\right)$, $a=16$ e $b=4$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2$, $c=64$, $a/b=\frac{1}{2}$ e $ca/b=64\cdot \left(\frac{1}{2}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=64\cdot 1$, $a=64$ e $b=1$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=64$, $b=2$ e $a/b=\frac{64}{2}$
