Converting an octal number to hexadecimal without a calculator involves first converting the octal number to binary, then grouping the binary digits into groups of four, and finally converting each group to its hexadecimal equivalent. Here's a step-by-step guide for octal number754:

Convert each octal digit to its 3-bit binary equivalent:

78 = 1112

58 = 1012

48 = 1002

Group the binary digits into groups of four, starting from the right. If the last group has fewer than four digits, pad it with zeros on the left.

Binary: 1 1110 1100

With Zeros: 0001 1110 1100

Convert each group of binary digits to its hexadecimal equivalent:
