Answer 1

a. 21 : 2 = 10 r 1
10 : 2 = 5 r 0
5 : 2 = 2 r 1
2 : 2 = 1

= 1 101

b. 23 : 2 = 11 r 1
11 : 2 = 5 r 1
5 : 2 = 2 r 1
2 : 2 = 1

= 1 111

c. 25 : 2 = 12 r 1
12 : 2 = 6 r 0
6 : 2 = 3 r 0
3 : 2 = 1 r 1

= 1 001

d. 26 : 2 = 13 r 0
13 : 2 = 6 r 1
6 : 2 = 3 r 0
3 : 2 = 1 R 1

= 1 010

e. 24 : 2 = 12 r 0
12 : 2 = 6 r 0
6 : 2 = 3 r 0
3 : 2 = 1 R 1

= 1 000

f. 27 : 2 = 13 r 1
13 : 2 = 6 r 1
6 : 2 = 3 r 0
3 : 2 = 1 R 1

= 1 011

g. 28 : 2 = 14 r 0
14 : 2 = 7 r 0
7 : 2 = 3 r 1
3 : 2 = 1 R 1

= 1 100

h. 29 : 2 = 14 r 1
14 : 2 = 7 r 0
7 : 2 = 3 r 1
3 : 2 = 1 R 1

= 1 101
