Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=26$, $b=615$, $c=0.0422741$, $a/b=\frac{26}{615}$ e $ca/b=0.0422741\left(\frac{26}{615}\right)$

Applicare la formula: $ab$$=ab$, dove $ab=0.0422741\cdot 26$, $a=0.0422741$ e $b=26$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=1.0991254$, $b=615$ e $a/b=\frac{1.0991254}{615}$
