Answer 1

Answer: (A)

$32.54$

The octal equivalent of the number 11010.1011 is 32.54

Octal. The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right). For example, the binary representation for decimal 74 is 1001010.

Octal (base-8) and hexadecimal (base-16) numbers are a reasonable compromise between the binary (base-2) system computers use and decimal (base-10) system most humans use. ... I think hex wins over octal because it can easily be used to represent bytes and 16/32/64-bit numbers.
