(i) To find the value of A, First divide the binary number (11011)2 into groups of 3 bits (starting from the right) Then write down the corresponding octal number of each group for this insert a zero (0) in the left side of the binary number.
(ii) To find the value of B, First divide the binary number (11011)2 into groups of 4 bits (starting from the right). Then write down the corresponding. Hexa decimal equivalent of each group. For this insert 3 zeroes in the left side of the binary number.
(iii) To find the value of C find the decimal equivalent so as to do the following.
(11011)2 = 1*24 + 1*23 + 0 * 22 + 1*21 + 1 *20
= 16 + 8 + 0 + 2+ 1
= (27)10
ie C = 27
