СРОЧНО помогите (3/4+1/6):3+(5/6-1/2):9 (3/4-5/12)*3-1/16:1/8

[latex]( frac{3}{4}+ frac{1}{6} ):3+( frac{5}{6} - frac{1}{2} ):9= ( frac{9}{12}+ frac{2}{12} ):3+( frac{5}{6} - frac{3}{6} ):9=[/latex][latex]= frac{11}{12}:3+frac{2}{6} :9= frac{11}{36} + frac{1}{27} = frac{33}{108} + frac{4}{108}= frac{37}{108} [/latex][latex]( frac{3}{4} - frac{5}{12} )*3- frac{1}{16}: frac{1}{8} =( frac{9}{12} - frac{5}{12} )*3- frac{1}{16}*frac{8}{1}= frac{4}{12}*3- frac{1}{2} =1- frac{1}{2}= frac{1}{2}[/latex]
