Решите уравнение 3 1/3: (3/7х -13/15)=1 19/16

14,51

Пошаговое объяснение:

3 1/3 : (3/7 X - 13/15) = 119/16

10/3 : 3/7 X - 10/3 : 13/15 = 119/16

10/3 x 7/3 X - 10/3 x 15/13 = 119/16

70/9 X - 150/39 = 119/16

43680/5616 X - 21600/5616 = 41769/5616

43680/5616 X = 41769/5616 + 21600/5616

43680/5616 X = 63369/5616

X = 63369/5616 : 43680/5616

X = 63369/5616 x 5616/43680 = 63369/43680 = 14,51
