Answer 1

12 : 2 = 6 + rest 0

6 : 2 = 3 + rest 0

3 : 2 = 1 + rest 1

1 : 2 = 0 + rest 1

citim resturile de jos in sus ↑

12(10) = 1100(2)

15 : 2 = 7 + 1

7 : 2 = 3 + 1

3 : 2 = 1 + 1

1 : 2 = 0 + 1

15(10) = 1111(2)

33 : 2 = 16 + 1

16 : 2 = 8 + 0

8 : 2 = 4 + 0

4 : 2 = 2 + 0

2 : 2 = 1 + 0

1 : 2 = 0 + 1

33(10) = 100001(2)

46 : 2 = 23 + 0

23 : 2 = 11 + 1

11 : 2 = 5 + 1

5 : 2 = 2 + 1

2 : 2 = 1 + 0

1 : 2 = 0 + 1

46(10) = 101110(2)

Answer 2

2₍₁₀₎ = 2+0 = 10₍₂₎

12₍₁₀₎ = 8+4+0+0 = 1100₍₂₎

15₍₁₀₎ = 8+4+2+1 = 1111₍₂₎

33₍₁₀₎ = 32+0+0+0+0+1 = 100001₍₂₎

46₍₁₀₎ = 32+0+8+4+2+0 = 101110₍₂₎
