1. (Binary)
0 1
0
1 0 1
“ 2”
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
“ 10”
12345
5
100
4 (101) 3
(102) 2
(103) 1 (104) 12345

2. 12345 = (1 x 104) + (2 x 103) + (3 x 102) + (4 x 101)
+ (5 x 100)
= 10000 + 2000 + 300 + 40 + 5
12.34
12.34 = (1 x 101) + (2 x 100) + (3 x 10-1) + (4 x 10-2)
= 10 + 2 + 0.3 + 0.04

1011.012
1011.012 = (1 x 23) + (0 x 22) + (1 x 21) + (1 x 20) + (0 x
2-1) + (1 x 2-2)
= 8 + 0 + 2 + 1 + 0 + 0.25
= 11.25
