1-49To convert a binary fraction to its octal equivalent, starting at the radix point and moving right,expand each digit into a group of three:Add 0s to the right of the LSD if necessary to form a group of three. Now write the octal digit foreach group of three, as shown below:To convert a mixed binary number, starting at the radix point, form groups of three both right andleft:Convert the following binary numbers to octal:Q65.10_{2}.Q66.1010_{2}.Q67.101111_{2}.Q68.0.0011_{2}.Q69.0.110011_{2}.Q70.110111.010101_{2}.Binary to HexThe table below shows the relationship between binary and hex numbers. You can see that fourbinary digits may be represented by one hex digit. This is because 16 is equal to 2^{4}.
