- B.
110001
- C.
100011
- D.
010101
- E.
001100
Correct Answer
C. 100011Explanation
To represent 35 in binary numbers, we need to convert it from decimal to binary. The binary number system uses only two digits, 0 and 1. Starting from the rightmost digit, we divide 35 by 2 and note the remainder. We continue this process until the quotient becomes 0. The remainders in reverse order give us the binary representation. In this case, the binary representation of 35 is 100011.Rate this question:

- D.
101000
- E.
100001
Correct Answer
E. 100001Explanation
The correct answer is 100001 because in binary representation, each digit can either be a 0 or a 1. To represent 33 in binary, we start from the right and assign the value of 1 to the first digit, which represents 2^0. Then, we assign the value of 0 to the second digit, which represents 2^1. Continuing this pattern, we assign the value of 0 to the third digit, representing 2^2, and so on. Finally, we assign the value of 1 to the sixth digit, representing 2^5. Adding up all these values, we get 33.Rate this question:

- E.
110101
Correct Answer
A. 111011Explanation
To represent a number in binary, we convert it into its binary equivalent. In this case, to represent 59 in binary, we start by dividing 59 by 2 and noting the remainder. We continue this process until the quotient becomes 0. The remainders, read in reverse order, give us the binary representation. In this case, the binary representation of 59 is 111011.Rate this question:
