2. (111000110010)₂ conversion base2 to base8 conversion
Equivalent value list
Binary to octal→
binary Octal
base2(binary)= 111000110010
base8(octal)= 7062 oct
000 0
So, (111000110010)₂=(7062)₈
001 1
binary to decimal→
Base8(octal)= 7062 010 2
= 7*8³+0*8²+6*8¹+2*8°
011 3
= 3634 dec
So, (111000110010)₂=(3634)₁₀
100 4
binary to hexadecimal →
101 5
remainder
3634/16= 227 2 in hexadecimal form 110 6
227/16 = 14 3 in hexademal form
14/16 = 0 14=E in hexadecimal form 111 7
So,(111000110010)₂=(E32)₁₆

3. (70642)₈ conversion
Octal to decimal→
Oct= 76042 = 7*8´+6*8³+0*8²+4*8¹+2*8° = 31778 dec
So, (76042)₈= (31778)₁₀
Decimal
Operation Quotient Remainder Binary Result
Number
octal to binary→ 31778 ÷2= 15889 0 0
15889 ÷2= 7944 1 10
7944 ÷2= 3972 0 010
3972 ÷2= 1986 0 0010

248 ÷2= 124 0 00100010
124 ÷2= 62 0 000100010
62 ÷2= 31 0 0000100010
31 ÷2= 15 1 10000100010
15 ÷2= 7 1 110000100010
7 ÷2= 3 1 1110000100010
3 ÷2= 1 1 11110000100010
1 ÷2= 0 1 111110000100010

4. Octal to hexadecimal→
(76042)₈= (31778)₁₀
Decimal operation quotient remainder
number
31778 ÷16 = 1986 2
1986 ÷16= 124 2
124 ÷16 = 7 12=C
7 ÷16= 0 7
0 Done.
So,
(76042)₈=(7C22)₁₆

5. (786)₁₀ conversion
Decimal to binary→
Decimal operation quotient remainder Binary result
number
786 ÷2= 393 0 0
393 ÷2= 196 1 10
196 ÷2= 98 0 010
98 ÷2= 49 0 0010
49 ÷2= 24 1 10010
24 ÷2= 12 0 010010
12 ÷2= 6 0 0010010
6 ÷2= 3 0 00010010
3 ÷2= 1 1 100010010
1 ÷2= 0 1 1100010010
So, (786)₁₀=(1100010010)₂

6. Decimal to octal→
