Applicare la formula: $ab$$=ab$, dove $ab=0.125\cdot 2\cdot \left(\frac{1}{3}\right)$, $a=\frac{1}{8}$ e $b=2$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=3$, $c=\frac{1}{4}$, $a/b=\frac{1}{3}$ e $ca/b=0.25\cdot \left(\frac{1}{3}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=0.25\cdot 1$, $a=\frac{1}{4}$ e $b=1$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=\frac{1}{4}$, $b=3$ e $a/b=\frac{0.25}{3}$
