The binary number 111010 converted to hexadecimal is ( ). A.7A B.72 C.3A D.32 Answer: C. 3A. Converting between binary and hexadecimal is very simple; to convert binary to hexadecimal, group the bits from the end in sets of four, and any result of 10 or higher is represented using the letters A through F. For this question, the binary number is grouped as 0011 1010; the sum of the first group is 3, and the sum of the second group is 10, which corresponds to A, so the hexadecimal value is 3A. Reply with the answer you think is correct in the comments to participate; +2 wealth points will be awarded automatically according to the rules. If your answer is incorrect, no additional points or feedback will be given. An additional +3 wealth points will be given if you answer all questions correctly. Extra wealth points will also be awarded if you provide a detailed explanation or analysis of the questions and answers. The answer will be visible after the reply.
