Applicare la formula: $a+b$$=a+b$, dove $a=\frac{9}{5}$, $b=\frac{3}{2}$ e $a+b=1.8+1.5+\frac{5}{14}$

Applicare la formula: $\frac{a}{b}+c$$=\frac{a+cb}{b}$, dove $a/b+c=3.3+\frac{5}{14}$, $a=5$, $b=14$, $c=\frac{33}{10}$ e $a/b=\frac{5}{14}$

Applicare la formula: $ab$$=ab$, dove $ab=3.3\cdot 14$, $a=\frac{33}{10}$ e $b=14$

Applicare la formula: $a+b$$=a+b$, dove $a=5$, $b=\frac{231}{5}$ e $a+b=5+46.2$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=\frac{256}{5}$, $b=14$ e $a/b=\frac{51.2}{14}$
