Question

Buna ! Ma puteti ajuta si pe mine la aceste exercitii :
c. 1,5 - 2,(3) -0,(6);
d. 0,(3) - 2,5 +7 supra 6
e. 4 - 1,(3) +1 supra 6;
f. -1,(3) - 16 supra 3 + 6,(6)
+ CORONITA

Answer 1

c. 1,5 - 2,(3) -0,(6)= 15/10-21/9-6/9=3/2-7/3-2/3=3/2-9/3=3/2-3=3/2-6/2= -3/2


d. 0,(3) - 2,5 +7/ 6= 3/9-25/10+7/6=1/3-5/2+7/6=2/6-15/6+7/6= -6/6=-1


e. 4 - 1,(3) +1/ 6= 4- 12/9+1/6= 4-4/3+1/6=24/6-8/6+1/6= 17/6

f. -1,(3) - 16 / 3 + 6,(6)= -12/9-16/3 +60/9= 48/9-16/3= 16/3-16/3=0
