Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=3$, $b=5$, $c=\frac{319}{25}$, $a/b=\frac{3}{5}$ e $ca/b=12.76\left(\frac{3}{5}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=12.76\cdot 3$, $a=\frac{319}{25}$ e $b=3$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=\frac{957}{25}$, $b=5$ e $a/b=\frac{38.28}{5}$
