problema 1
\[
\begin{array}{l}
\frac{3}{4}din320 = \left( {320:4} \right)x3 = 240{\rm I}zi \\
\frac{1}{8}din320 = \left( {320:8} \right)x1 = 40{\rm I}{\rm I}zi \\
320 – 280 = 40{\rm I}{\rm I}{\rm I}zi \\
\end{array}
\]
problema2
\[
\begin{array}{l}
52×3 = 156 nr locuri \\
\frac{4}{6}din156 = \left( {156:6} \right)x4 = 104 locuri clasa a4a \\
156 – 104 = 52 nr.locuri clasa a3a \\
\end{array}
\]
sincer nu am inteles nimic.
te rog fi mai explicit.
