please show work so I can understand how to do the problem

(5) (a) What is the largest decimal number that can be sent in 3 bits using the serial data method? (b) What is the largest decimal number that can be sent in one byte using the serial data method? (c) What is the largest decimal number that can be sent in 12 bits using the serial data method? (6) An electrochemistry experiment communicates with a computer using digital signal transmission. The number 50 is used to represent an electrical current of 50 milliamps (mA). Assume it takes 2.25 ns to transmit a single bit of data. (a) How long does it take to transmit the number 50 in serial form? (5) (a) What is the largest decimal number that can be sent in 3 bits using the serial data method?
