1) 12 asas 10
= 1x2^3 + 1x2^2 + 0x2^1 + 0x2^0
= 8 + 4 + 0 + 0
= 12

maka, jawapannya 1100 asas 2

2) 13 asas 10
= 1x2^3 + 1x2^2 + 0x2^1 + 1x2^0
= 8 + 4 + 0 + 1
= 13

maka, jawapannya 1101 asas 2

3) 20 asas 10
= 1x2^4 + 0x2^3 + 1x2^2 + 0x2^1 + 0x2^0
= 16 + 0 + 4 + 0 + 0
= 20

maka, jawapannya 10100 asas 2

4) 50 asas 10
= 1x2^5 + 1x2^4 + 0x2^3 + 0x2^2 + 1x2^1 + 0x2^0
= 32 + 16 + 0 + 0 + 2 + 0
= 50

maka, jawapannya 110010 asas 2

5) 101 asas 10
= 1x2^6 + 1x2^5 + 0x2^4 + 0x2^3 + 1x2^2 + 0x2^1 + 1x2^0
= 64+ 32 + 0 + 0 + 4 + 0 + 1
= 101

maka, jawapannya 1100101 asas 2
