What will be the answer if you convert 75 to binary?
Correct Answer
C. 1001011
Explanation
To convert a decimal number to binary, we repeatedly divide the decimal number by 2 and note down the remainder. We continue this process until the quotient becomes zero. Then, we write down the remainders in reverse order to obtain the binary equivalent. In this case, when we convert 75 to binary, we get the binary number 1001011.
44.
What will be the answer if you conver 11010110 to decimal
