To represent an eight-digit decimal number in Binary-Coded Decimal (BCD), each decimal digit is encoded using 4 bits. Since there are 8 digits in the number, the total number of bits required is 8 digits × 4 bits/digit = 32 bits. Therefore, 32 bits are needed to represent an eight-digit decimal number in BCD.
For the simple reason that the 'places' in a binary number represent multiples of 2, rather than 10. Therefore, a binary '10' = a decimal '2.'
It takes 7 digits.
The decimal number 166 can be represented as a binary number by converting it through repeated division by 2. The binary equivalent of 166 is 10100110. This means that in binary, 166 is composed of 1s and 0s that represent powers of 2.
The binary number 10000000 represents the decimal 128

The binary equivalent for the decimal number 23 is 10111
10111
All I know is that when a number is negative, you convert the decimal into binary and if it is negative you put 1111 before the binary digits.
10 digits.

If that's binary, it's 57 base 10
It takes 7 digits.

The decimal number 101 is represented by the binary number 1100101.
Every decimal number can be represented by a binary number - and conversely.
