Question

(10011001) to octal and base 5
​

Answer 1

Answer:

231

Step-by-step explanation:

(10011001)2 = (231)8

Step by step solution

Step 1: Write down the binary number

(010011001)2

Group all the digits in sets of three starting from the LSB (far right). Add zeros to the left of the last digit if there aren't enough digits to make a set of three.

010 011 001

Step 2: Use the table below to convert each set of three into an octal digit. In this case,

010=2, 011=3, 001=1.

So, the number 231 is the octal equivalent to 10011001 in binary.

To convert from binary to octal use the following table:

Bin: 000 001 010 011 100 101 110 111

Octal: 0 1 2 3 4 5 6 7
