Answer 1

Answer:example

Explanation:

First convert it into binary or hexadecimal number,

= (98)10

= (1x26+1x25+0x24+0x23+0x22+1x21+0x20)10  or   (6x161+2x160)10

Because base of binary and hexadecimal are 2 and 16 respectively.

= (1100010)2   or   (62)16

Then convert each digit of hexadecimal number into 4 bit of binary number whereas convert each group of 3 bits from least significant in binary number.

= (001 100 010)2   or   (0110 0010)2

= (001 100 010)2

= (1 4 2)8

= (142)8

Divide the decimal number by the largest power of eight.

= 136 / 64 = 2.125

So 2 will be first digit or most significant bit (MSB) of octal number.

Now, remainder will be,

= 136 - 642 = 8

Now, divide this remainder by the next power of 8.

= 8 / 8 =1.0

So 1 will be next digit or second most significant bit (MSB) of octal number.

Now, remainder will be,

= 8 - 81 = 0

Now, divide this remainder by the next power of 8.

= 0 / 8 = 0

So, 0 will be last (least significant) bit of required octal number.

Therefore, 210 will be equivalent octal number of given decimal number 136.
