Answer 2

(i) 40 + 6 + 710 + 9100

(ii) 500 + 70 + 8 + 310 + 1100 + 61000

(iii) 700 + 30 + 1 + 810 + 4100

(iv) 600 + 5 + 7100 + 91000

(v) 800 + 5 + 810 + 61000

(vi) 30 + 9 + 4100 + 81000

ANSWER:

(i) 40 + 6 + 710 + 9100 = 46 + 0.7 + .09 = 46.79

(ii) 500 + 70 + 8 + 310 + 1100 + 61000 = 578 + 0.3 + 0.01 + 0.006 = 578.316

(iii) 700 + 30 + 1 + 810 + 4100 = 731 + 0.8 + 0.04 = 731.84

(iv) 600 + 5 + 7100 + 91000 = 605 + 0.07 + 0.009 = 605.079

(v) 800 + 5 + 810 + 61000 = 805 + 0.8 + 0.006 = 805.806

(vi) 30 + 9 + 4100 + 81000 = 39 + 0.04 + 0.008 = 39.048

(iii) 1.6, 0.07, 3.58, 2.9

(iv) 2.5, 0.63, 14.08, 1.637

ANSWER:

(i) Each of the numbers has maximum 3 decimal places. So, we convert them into numbers having three decimal places by annexing suitable number of zeroes to the extreme right of the decimal part.

7.5 = 7.500

64.23 = 64.230

0.074 = 0.074

(ii) Each of the numbers has maximum 3 decimal places. So, we convert them into numbers having three decimal places by annexing suitable number of zeroes to the extreme right of the decimal part.

0.6 = 0.600

5.937 = 5.937

2.36 = 2.360

4.2 = 4.200

(iii) Each of the numbers has maximum 2 decimal places. So, we convert them into numbers having three decimal places by annexing suitable number of zeroes to the extreme right of the decimal part.

1.6 = 1.60

0.07 = 0.07

3.58 = 3.58

2.9 = 2.90

(iv) Each of the numbers has maximum 3 decimal places. So, we convert them into numbers having three decimal places by annexing suitable number of zeroes to the extreme right of the decimal part.

2.5 = 2.500

0.63 = 0.630

14.08 = 14.080

1.637 = 1.637

I hope this will help you !
