Ответ:
[tex]\frac{5}{8} -\frac{7}{12} =\frac{15}{24}-\frac{14}{24} =\frac{1}{24}\\ \\ 4\frac{5}{9} -2\frac{2}{3} = 4\frac{5}{9} -2\frac{6}{9} = 3\frac{14}{9} -2\frac{6}{9} = 1\frac{8}{9}[/tex]
Пошаговое объяснение:
5/8 - 7/12 = (5*3)/(8*3) - (7*2)/(12*2) = 15/24 - 14/24 =
(15-14)/24 = 1/24
4 5/9 - 2 2/3 = 4 5/9 - 2 (2*3)/(3*3) = 4 5/9 - 2 6/9 =
3 14/9 - 2 6/9 = 1 8/9
