Applicare la formula: $\frac{a}{b}+c$$=\frac{a+cb}{b}$, dove $a/b+c=\frac{8}{5}+8.25$, $a=8$, $b=5$, $c=\frac{33}{4}$ e $a/b=\frac{8}{5}$

Applicare la formula: $ab$$=ab$, dove $ab=8.25\cdot 5$, $a=\frac{33}{4}$ e $b=5$

Applicare la formula: $a+b$$=a+b$, dove $a=8$, $b=\frac{165}{4}$ e $a+b=8+41.25$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=\frac{197}{4}$, $b=5$ e $a/b=\frac{49.25}{5}$
