To convert a binary number to octal: 1) Separate the binary number into groups of 3 digits from the right. 2) Convert each 3-digit group to its octal equivalent. 3) The octal number is the combination of each converted group from right to left.

6. =

7. Answer: 105
7

8. 8
S = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

12. Example: convert the number 111,base 10 to octal.
738
9
1
8
1
1
7310 = 1118

13.  The conversion between binary and octal is quite simple.
 Since 2 to the power of 3 equals 8, it takes 3 base 2 digits to
combine to make a base 8 digit.
 000 base 2 equals 0 base 8
0012 = 18
0102 = 28
0112 = 38
1002 = 48
1012 = 58
1102 = 68
1112 = 78

14.  What if you have more than three
binary digits, like 110011?
 Just separate the digits into groups of
three from the right, then convert
each group into the corresponding
base 8 digit.
 110 011 base 2 = 63 base 8
 1100101 = 1 100 101 = 001 100 101
