Convert 491 into binary number
sergij07 [2.7K]

Answer:

111101011 subscript 2

Step-by-step explanation:

491 / 2 = 245 , 1 remainder

245 / 2 = 122 , 1 remainder

122 / 2 = 61 , 0 remainder

61 / 2 = 30 , 1 remainder

30 / 2 = 15 , 0 remainder

15 / 2 = 7 , 1 remainder

7 / 2 = 3 , 1 remainder

3 / 2 = 1 , 1 remainder

1 / 2 = 0 , 1 remainder

Now, we're going to put the remainders together in reverse order to get the final answer.

111101011 ---> this is the final solution

See the image below for how you would write 111101011 subcript 2.
