Question

ajutatima si pe mine  va rog :)

Answer 1

-1intreg3/5=(-1)(1·5+3)/5=-8/5
0,(45)=45/99=simplif.cu 9=5/11
-2,(3)=(-1)(23-2)/9=-21/9= simplif.cu 3=-7/3
-1,15=-115/100=simplif.cu ·25=-5/4
deci A={-3,-5/6,+5/9,-8/5,+5/11,-7/3,-5/4,+3}
(-3)la put.-1=-1/3
(-5/6)la put.-1=-6/5
+5/9la put.-1=9/5 s.a.m. d
B={-1/3,-6/5,+9/5,-5/8,+11/5,-3/7,-4/5,+1/3}
