5/6 + 1 2/3= 5/6 + 1 i 4/6 = 1 i 9/6 = 1 i 3/2 = 2 i 1/2
1-1/2 x 1/3= 1 - 1/6 = 6/6 - 1/6 = 5/6
[tex]\frac{5}{6} + 1 \frac{2}{3} = \frac{5}{6} + \frac{5}{3} = \frac{5}{6} + \frac{10}{6} = \frac{15}{6} = 2 \frac{3}{6} = 2 \frac{1}{2} \\ \\ 1 - \frac{1}{2} \cdot \frac{1}{3} = 1 - \frac{1}{6} = \frac{6}{6} - \frac{1}{6} = \frac{5}{6}[/tex]
