How can we Convert the following decimal numbers to BCD code and then attach an odd parity bit. (a)74 (c)8884 (e)165 (b) 38 (d) 275 (f) 9201?

To convert decimal numbers to Binary-Coded Decimal (BCD), each digit is represented by its 4-bit binary equivalent. For instance, 74 in BCD is 0111 0100, 38 is 0011 1000, 8884 is 1000 1000 1000 0100, 275 is 0010 0111 0101, 165 is 0001 0110 0101, and 9201 is 1001 0010 0000 0001. To add an odd parity bit, count the number of 1s in the BCD representation; if it's even, add a 1, and if it's odd, add a 0. For example, 74 becomes 0111 0100 1 (5 ones), and 38 becomes 0011 1000 1 (5 ones).
