Answer 1

(a) 0 x 100 + 0 x 10 + 3 x 1 + 2 x 1/10 + 5 x 1/100 + 0 x 1/1000 

= 0 + 0 + 3 + 0.2 + 0.05 + 0 = 3.25 

(b) 1 x 100 + 0 x 10 + 2 x 1 + 6 x 1/10 + 3 x 1/100 + 0 x 1/1000

= 1 + 0 + 2 + 0.6 + 0.03 + 0 = 102.63 

(c) 0 x 100 + 3 x 10 + 0 x 1 + 0 x 1/10 + 2 x 1/100 + 5 x 1/1000

= 0 + 30 + 0 + 0 + 0.02 + 0.005 = 30.025 

(d) 2 x 100 + 1 x 10 + 1 x 1 + 9 x 1/10 + 0 x 1/100 + 2 x 1/1000

= 200 + 10 + 1 + 0.9 + 0 + 0.002 = 211.902 

(e) 0 x 100 + 1 x 10 + 2 x 1 + 2 x 1/10 + 4 x 1/100 + 1 x 1/1000 

0 + 10 + 2 + 0.2 + 0.04 + 0.001 = 12.241
