Explicație pas cu pas:
se face imparind nr la 2 si continuand cu catul impartit la 2 Apoi se citesc resturile de jos in sus
-
a)
9:2=4 rest 1
4:2=2 rest 0
2:2=1 rest 0
1:2= 0 rest 1
-
citim si scriem resturile de jos in sus si obtinem
9₍₁₀₎ = 1001₍₂₎
-
b)
43:2=21 rest 1
21:2=10 rest 1
10:2=5 rest 0
5:2=2 rest 1
2:2=1 rest 0
1:2=0 rest 1
-
43₍₁₀⁾= 101011 ₍₂₎
-
c)
137:2=68 rest 1
68:2=34 rest 0
