Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2860$, $c=\frac{348}{25}$, $a/b=\frac{1}{2860}$ e $ca/b=13.92\left(\frac{1}{2860}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=13.92\cdot 1$, $a=\frac{348}{25}$ e $b=1$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=\frac{348}{25}$, $b=2860$ e $a/b=\frac{13.92}{2860}$
