Odpowiedź:
[tex]6\frac{1}{12}-x=4\frac{1}{4}\\x= 6\frac{1}{12}-4\frac{3}{12}=5\frac{13}{12}-4\frac{3}{12}=1\frac{10}{12}=1\frac{5}{6}[/tex]
Szczegółowe wyjaśnienie:
[tex]6 \frac{1}{12} - x = 4 \frac{1}{4} \\ \\ - x = 4 \frac{1}{4} - 6 \frac{1}{12} \\ \\ - x = \frac{17}{4} - \frac{73}{12} \\ - x = \frac{51}{12} - \frac{73}{12} \\ x = \frac{11}{6} \\ x = 1 \frac{5}{6} [/tex]
