Answer:
13 = 1101
100 = 1100100
255 = 11111111
17 = 10001
156 = 10011100
Step-by-step explanation:
for the conversion from denary to binary, divide the number by 2 and note down the remainder (1 or 0)
13
2 13
2 6 - 1
2 3 - 0
1 - 1
thus 13 in binary = 1101
100
2 100
2 50 - 0
2 25 - 0
2 12 - 1
2 6 - 0
2 3 - 0
1 - 1
thus 100 in binary = 1100100
255
2 255
2 127 - 1
2 63 - 1
2 31 - 1
2 15 - 1
2 7 - 1
2 3 - 1
1 - 1
thus 255 in binary = 11111111
17
2 17
2 8 - 1
2 4 - 0
2 2 - 0
1 - 0
thus 17 in binary = 10001
156
2 156
2 78 - 0
2 39 - 0
2 19 - 1
2 9 - 1
2 4 - 1
2 2 - 0
1 - 0
thus 156 in binary = 10011100
