Answer 2

Answer:

3.5 – 2.43 + 0.075

(ii) 7.84 + 0.3 – 4.016

(iii) 2.987 – 1.25 – 0.54

(iv) 52.9 – 231.666 + 204

(v) 8.57 – 6.4432 – 1.70 + 0.683

Solution:

(i) 3.5 - 2.43 + 0.075

= 3.5000 + 0.075 - 2.43

= 3.575 - 2.430 = 1.145

(ii) 7.84 + 0.3 - 4.016

= 7.840 + 0.300 - 4.016

= 8.140 - 4.016

= 4.124

(iii) 2.987 - 1.25 - 0.54

= 2.987 - 1.79

= 1.197

(iv) 52.9 - 231.666 + 204

= 52.9 - 231.666 + 204.0

= 256.9 - 231.666

= 256.900 - 231.666

= 25.234
