А) 5/8-1/2=. Б) 7/8-11/24=. В) 17/18-5/6=. Г) 777/1000-1/10= Подробное решение помогите пожалуйста

[latex] \frac{5}{8}- \frac{1}{2} =\frac{5}{8}- \frac{1*4}{2*4} =\frac{5}{8}-\frac{4}{8}=\frac{1}{8};[/latex] [latex]\frac{7}{8}-\frac{11}{24}=\frac{7*3}{8*3}-\frac{11}{24}=\frac{21}{24}-\frac{11}{24}=\frac{10}{24}=\frac{5}{12};[/latex] [latex]\frac{17}{18}-\frac{5}{6}=\frac{17}{18}-\frac{5*3}{6*3}=\frac{17}{18}-\frac{15}{18}=\frac{2}{18}=\frac{1}{9};[/latex] [latex]\frac{777}{1000}- \frac{1}{10} =\frac{777}{1000}- \frac{1*100}{10*100} =\frac{777}{1000}- \frac{100}{1000} =\frac{677}{1000};[/latex]

а) 5/8-1/2=5/8-4/8=1/8 б)7/8-11/24=21/24-11/24=10/24=5/12 в) 17/18-5/6=17/18-15/18=2/18= 1/9 г) 777/1000-1/10=777/1000- 100/1000=677/1000
