Решите примеры, , ! (3 5/6 - 2 3/4) : 7/12+8.5= 2 1/7•(2 2/3 + 2 2/15)-8.8= (1 2/3 : 2/3 - 0.12 : 1/2)•0.5= (16.2 - 1 14/15) : (1 5/7+ 3 8/12)=

(35/6 -23/4): 7/12+8.5= 8 9/14.
1) 35/6 - 23/4= 5 5/6 - 5 3/4= 5 10/12 - 5 9/12=1/12
2)1/12 : 7/12= 1/12 • 12/7= 1/7
3) 1/7 + 8.5= 1/7+8 1/2= 2/14 + 8 7/14= 8 9/14
