Answer 1

Răspuns:

10 : 2 = 5 + 0

5 : 2 = 2 + 1

2 : 2 = 1 + 0

1 : 2 = 0 + 1

10=1010

15 : 2 = 7 + 1

7 : 2 = 3 + 1

3 : 2 = 1 + 1

1 : 2 = 0 + 1

15= 1111

45 : 2 = 22 + 1

22 : 2 = 11 + 0

11 : 2 = 5 + 1

5 : 2 = 2 + 1

2 : 2 = 1 + 0

1 : 2 = 0 + 1

45= 101101

132 : 2 = 66 + 0

66 : 2 = 33 + 0

33 : 2 = 16 + 1

16 : 2 = 8 + 0

8 : 2 = 4 + 0

4 : 2 = 2 + 0

2 : 2 = 1 + 0

1 : 2 = 0 + 1

132 =10000100

200 : 2 = 100 + 0

100 : 2 = 50 + 0

50 : 2 = 25 + 0

25 : 2 = 12 + 1

12 : 2 = 6 + 0

6 : 2 = 3 + 0

3 : 2 = 1 + 1

1 : 2 = 0 + 1

200=11001000

Answer 2

Explicație pas cu pas:

10:2 = 5 rest 0

5:2 = 2 rest 1

2:2 = 1 rest 0

1:2 = 0 rest 1

$\implies \bf 10_{10} = 1010_{2}$

15:2 = 7 rest 1

7:2 = 3 rest 1

3:2 = 1 rest 1

1:2 = 0 rest 1

$\implies \bf15_{10} = 1111_{2}$

$45_{10} = 101101_{2}$

$132_{10} = 10000100_{2}$

$200_{10} = 11001000_{2}$
