Convert each section using the formula b * 2^2 + b * 2^1 + b* 2^0 and you get the octal number 766. Similarly, 2^4 = 16 so to convert a number from binary to hexadecimal all that is necessary is to start at the right of the number, mark off 4 bits, convert those bits to decimal. The resulting number is the hexadecimal equivalent. Take the binary number 10101001. Break it up into sections of 4 bits each: 1010 1001 Convert each section using the formula b * 2^3 + b * 2^2 + b * 2^1 + b* 2^0 and you get the hexadecimal number A9. Convert the following binary numbers to octal: 1000001 = ?10000010 =? 1100010 =? Convert the following binary numbers to hexadecimal: 11100111 =? 01101110 = ? 01111111 = ?
