\frac{^{4)}1}{~~3}= \frac{4}{12} \Longrightarrow \text{Primul copil primeste 4 parti.} \\\\
\frac{^{3)}1}{~~4}= \frac{3}{12} \Longrightarrow \text{Al doilea copil primeste 3 parti.} \\\\
\frac{^{2)}1}{~~6}= \frac{2}{12} \Longrightarrow \text{Al treilea copil primeste 2 parti.} \\\\
\text{In total copii primesc 4 + 3 + 2 = 9 parti din cele 12 parti.}\\\\
