A) =(60/8+11/8)-1=77/8-1=9,625-1=8,625
b) =105-(160/100+11/100)=105-171/100=105-1,71=104,29
c) =(21/11-25/11)+(121/11+1/11)= -4/11 + 122/11= 118/11

(15/2+11/8)-1=(60/8+11/8)-1=(71/8)-1= 7.875
105-(16/10+11/100)=105-(160/100+11/100)=105-(171/100)=103.29
(1 1/11-2 3/11)+(11+1/11)=-1,18+11 1/11=9,9109
