Question

Scrieti partea intreaga si partea fractionara a numarului 0,85 , -5,86 , -3,9 , 4,93(29) si -0,(5) .

Answer 1

$\it [0,85]=0;\ \ \ \{0,85\} =0,85\\ \\\ [ -5,86 ]= -5\ \ \ \ \ \{-5,86\}=-586-(-6)=6-5,86=0,14\\ \\ \Big[4,93(29) \Big] =4;\ \ \ \ \{4,93(29)\}=0,93(29)\\ \\ \\ \Big[-0,(5)\Big]=-1;\ \ \ \ \ \{-0,(5)\}=-0,(5)-(-1)=1-0,(5)=1-5/9=4/9$
