1. OBLICZAM LICZNIK:
1 [tex]\frac{5}{12}[/tex] = [tex]\frac{17}{12}[/tex]
-1[tex]\frac{1}{6} = -[/tex][tex]\frac{7} {6}[/tex]
[tex]\frac{17}{12}[/tex] : (-[tex]\frac{7} {6}[/tex]) =
[tex]2\frac{1}{2} = \frac{5}{2}[/tex]
[tex]\frac{2}{7}*\frac{5}{2} = \frac{5}{7}[/tex]
[tex]\frac{5}{7} = \frac{10}{14}[/tex]
[tex]-\frac{17}{14} +\frac{10}{14} =-\frac{7}{14}[/tex] (ostateczna wartość licznika przedstawiona za pomocą ułamka niewłaściwego)
2. OBLICZAM MIANOWNIK
[tex]4\frac{2}{3} = \frac{14}{3} \\7 = \frac{7}{1} \\\frac{14}{3} * \frac{1}{7} = \frac{2}{3} \\\\1\frac{1}{6} =\frac{7}{6} \\\frac{7}{6} * (-\frac{2}{7}) = -\frac{1}{3} \\\frac{2}{3} - \frac{1}{3} = \frac{1}{3}[/tex]
[tex]-\frac{7}{14}[/tex] * [tex]\frac{3}{1}[/tex] = [tex]- \frac{21}{14} = -\frac{3}{2} =-1\frac{1}{2}[/tex] = -1,5
