Cât de repede se poate

Answer 1

Explicație pas cu pas:

51:2 = 25 rest 1

25:2 = 12 rest 1

12:2 = 6 rest 0

6:2 = 3 rest 0

3:2 = 1 rest 1

1:2 = 0 rest 1

$\implies \bf 51_{10} = 110011_{2}$

127:2 = 63 rest 1

63:2 = 31 rest 1

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

$\implies \bf 127_{10} = 1111111_{2}$

75:2 = 37 rest 1

37:2 = 18 rest 1

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

$\implies \bf 75_{10} = 1001011_{2}$

47:2 = 23 rest 1

23:2 = 11 rest 1

11:2 = 5 rest 1

5:2 = 2 rest 1

2:2=1 rest 0

1:2=0 rest 1

$\implies \bf 47_{10} = 101111_{2}$
