(ii)Show how the number, 20 can be represented using the above system

. The owner of a small shop selling electronic components has purchased a microcomputer to produce
ivoices for customers. The numeric data item included in this invoices are:
Prices and total of iterns purchased, e.g. 4700.24 FCFA
Quantities of items purchased e.g. 2.
) Integers can be represented inside the microcomputer in locations of size 16 bits using
: Binary coded decimals;
: Sign and magnitude;
: Two's complement
Show how the number 20 would be represented using method A
Show how the number -20 will be represented using method B and C.
) Real numbers inside this computer using the 16 bits in the following form: The leftmost 10 bits are
ed to represent the mantissa and the remaining 6 bits represent the exponent. The 10 bits mantissa is
ored in sign and magnitude representation. The leftmost bit is the sign bit. The binary point is

immediately to the right of the sign bit. The exponent occupies six bits and is represented as an integer in
two's complement form. Show how the number 20.5 can be represented using this system.
