Question

Convert binary 010101 to octal

Answer 1

Answer:

25

Step-by-step explanation:

010=2, 101=5. So, the number 25 is the octal equivalent to 10101 in binary.

Answer 2

Answer: The correct answer is 25

Step-by-step explanation:

we know that to convert a binary number into octal number system:

      step 1 : group the digits in the binary numbers in the groups of 3 (without changing the order)

       step2: convert each of these group of 3 digit binary numbers to their decimal equivalent

       step3: after converting each of group of 3 digit binary numbers into decimal numbers write these numbers next to each other in the same order

so to convert binary 010101 to octal:

       step 1:        010 101

       step 2:

             (i) converting binary 010 to decimal = $((2^{2} * 0) + (2^{1}*1) + (2^{0}*0))$

                                                                          = (0 + 2 + 0) = 2

              (ii) converting binary 010 to decimal = $((2^{2} * 1) + (2^{1}*0) + (2^{0}*1))$

                                                                          = ( 4 + 0 + 1) = 5

       step 3:

                    010 101

                      2   5

                   = 25
