K = 25 / 256
------------------------
1) 5 1/4 - 6 1/6 = 5 3/12 - 6 2/12= 5 3/12 + (- 6 2/12)= 5 3/12+(-5 14/12)=- 11/12
2) 3 1/4-0.55 = 3 1/4 - 55/100 = 3 25/100 - 55/100=2 70/100 = 2 7/10
3) -11/12•2 7/10= - 11/12 • 27/10 = -99/40=-2/1940
36366-17366:(200-162)=35909
1)200-162=38
2)17366:38=457
3)36366-457=35909
8м=80дм
80-4=76дм
Вроде бы так.
