[tex]\frac{5}{6}-\frac{3}{4} = \frac{(5)(4)-(6)(3)}{(6)(4)} = \frac{20-18}{24} = \frac{2}{24} =\frac{1}{12}[/tex]
b)
[tex]\frac{5}{3}+\frac{1}{6} = \frac{(5)(6)+(3)(1)}{(3)(6)} = \frac{30+3}{18} = \frac{33}{18} =\frac{11}{6}[/tex]
c)
[tex]\frac{2}{3}+\frac{3}{5} -1= \frac{(2)(5)+(3)(3)}{(3)(5)}-1 = \frac{10+9}{15}-1 = \frac{19}{15}-1\\\\ \frac{19-(15)(1)}{15} = \frac{19-15}{15} = \frac{4}{15}[/tex]
