Show that the octal expansion of a positive integer can be obtained from its binary expansion by grouping together blocks of three binary digits, adding initial zeros if necessary, and translating each block of three binary digits into a single octal digit.

Solution Step 1To Show that the octal expansion of a positive integer can be obtained by first converting positive integer into its binary equivalent and then grouping binary digits into a group of 3 from the least significant bit( LSB).
