Answer:
To convert from octal to binary, start by breaking down the octal number into its individual digits. For example, 011 is composed of the digits 0, 1, and 1. Next, look up each of the octal digits in a binary conversion table to determine what each digit is in binary. For example, 0 in octal is 000 in binary, 1 in octal is 001 in binary, and 1 in octal is 001 in binary. Finally, combine the individual binary digits together to form the binary equivalent of the octal number. In this case, 011 in octal is 111 in binary.
