$$ \begin{array}{ll}1.4+2,1 & 	ext { b. } 1,6+0,5 \ 5.2-3.5 & 	ext { b. } 4,3-2.8\end{array} $$

I risultati delle operazioni sono: 1. $$ 1.4 + 2.1 = 3.5 $$ 2. $$ 1.6 + 0.5 = 2.1 $$ 3. $$ 5.2 - 3.5 = 1.7 $$ 4. $$ 4.3 - 2.8 = 1.5 $$

\( \begin{array}{ll}1.4+2,1 & \text { b. } 1,6+0,5 \\ 5.2-3.5 & \text { b. } 4,3-2.8\end{array} \)
