1:2=0 rest 1

$\implies \bf 2_{10} = 10_{2}$

3:2=1 rest 1

1:2=0 rest 1

$\implies \bf 3_{10} = 11_{2}$

4:2=2 rest 0

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 4_{10} = 100_{2}$

8:2=4 rest 0

4:2=2 rest 0

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 8_{10} = 1000_{2}$

9:2=4 rest 1

4:2=2 rest 0

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 9_{10} = 1001_{2}$

11:2=5 rest 1

5:2=2 rest 1

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 11_{10} = 1011_{2}$

35:2=17 rest 1

17:2=8 rest 1

8:2=4 rest 0

4:2=2 rest 0

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 35_{10} = 100011_{2}$

72:2=36 rest 0

36:2=18 rest 0

18:2=9 rest 0

9:2=4 rest 1

4:2=2 rest 0

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 72_{10} = 1001000_{2}$

31:2=15 rest 1

15:2=7 rest 1

7:2=3 rest 1

3:2=1 rest 1

1:2=0 rest 1

$\implies \bf 31_{10} = 11111_{2}$

b)

$5_{10} = 101_{2}$

$12_{10} = 1100_{2}$

$10_{10} = 1010_{2}$

$6_{10} = 110_{2}$

$7_{10} = 111_{2}$

$13_{10} = 1101_{2}$

$14_{10} = 1110_{2}$

$21_{10} = 10101_{2}$
