Quizplus · Accepted Answer

To convert the binary number $10111101_2$ to its octal equivalent, group the binary digits into sets of three, from right to left. If necessary, add leading zeros to make the last group a set of three. For $10111101_2$, we group it as $101\; 111\; 101$. Converting each group to its octal equivalent: $101_2 = 5_8$, $111_2 = 7_8$, and $101_2 = 5_8$. Therefore, $10111101_2 = 275_8$.
