DEC31 to Hex
Explanation
The given answer "1F, 1f" is the hexadecimal representation of the decimal number 31. In hexadecimal, the digits range from 0 to 9, followed by A to F representing the values 10 to 15. The uppercase "F" and lowercase "f" both represent the value 15 in hexadecimal. Therefore, "1F" and "1f" are both valid representations of the decimal number 31 in hexadecimal.Rate this question:

BIN 11101 = ? DEC
Explanation
The given binary number "BIN 11101" can be converted to decimal by multiplying each digit with its corresponding power of 2 and adding them together. In this case, starting from the rightmost digit, we have 1*2^0 + 0*2^1 + 1*2^2 + 1*2^3 + 1*2^4 = 1 + 0 + 4 + 8 + 16 = 29. Therefore, the decimal equivalent of "BIN 11101" is 29.Rate this question:

BIN 1010101 = ? DEC
Explanation
The given binary number 1010101 can be converted to decimal by multiplying each digit with the corresponding power of 2 and then adding them together. In this case, the calculation would be: (1*2^6) + (0*2^5) + (1*2^4) + (0*2^3) + (1*2^2) + (0*2^1) + (1*2^0) = 64 + 0 + 16 + 0 + 4 + 0 + 1 = 85. Therefore, the correct answer is 85.Rate this question:

BIN 100011 = ? DEC
Explanation
The given binary number, 100011, can be converted to decimal by multiplying each digit by its corresponding power of 2 and then adding the results. In this case, starting from the rightmost digit, we have 1*2^0 + 1*2^1 + 0*2^2 + 0*2^3 + 0*2^4 + 1*2^5 = 1 + 2 + 0 + 0 + 0 + 32 = 35. Therefore, the decimal equivalent of the binary number 100011 is 35.Rate this question:

DEC 7 = ? BIN
Explanation
The given question is asking for the decimal equivalent of the binary number 111. In binary, each digit can have a value of either 0 or 1, and the place values increase by powers of 2 from right to left. So, in this case, the binary number 111 represents 1*2^2 + 1*2^1 + 1*2^0 = 4 + 2 + 1 = 7 in decimal. Therefore, the correct answer is 111.Rate this question:
