Homework
1. a)123/2= 61,5; 61/2=30,5; 30/2=15; 15/2=7,5; 7/2= 3,5; 3/2=1,5
(1111011)
0.456*2=0.912; 0,912*2=1,824; 0,824*2=1,648; 0,648*2=1,296;
0,296*2=0,592; 0,592*2=1,184; 0,184*2=0,368; 0,368*2=0,736;
(0,736*2=1,472; 0,472*2=0,944; 0,944*2=1,888)
So
b)123/16= 7,6875 ; 0,6875*16=11 ; 7/16 is less than one, then hex is 7B
0,456*16= 7,296 ; 0,296*16=4,736; 0,736*16=11,776; 0,776*16=12,416;
0,416*16=6,656; 0,656*16=10,496; 0,496*16=7,936; 0,936*16=14,976;
0,976*16=15,616; 0,616*16=9,856; 0,856*16=13,696; 0,696*16=11,136;
0,136*16=2,176; 2,176*16=2,816; 0,816*16=13,056
Hex is 7B.74BC6A7EF9DB22D
c) 123,456/5=24,6912/5=4,93824/5=0,987648
0,987648*5=4,93824; 0,93824*5=4,6912; 0,6912*5=3,456; 0,456*5=2,28;
0,28*5=1,4; 0,4*5=2; 0*5=0
base-5 is
d)BCD is
2. a) Unsigned 16-bit binary is 0000000001101011. Hexadecimal is 6B
b) Unsigned 16-bit binary is 0000000...
