THE MEANING OF DECIMALS PROBLEMS 3 To see the answer, pass your mouse over the colored area. 15. In our system of numbering, what is the function of 0? 0 signifies that the unit at that position is absent. 0 holds the digit 16. 0's on the right of a decimal, or on the left of a whole number, do not add 16. Therefore, rewrite each number and eliminate the unnecessary zeros. 16. a) 3.2000 = 3.2 b) 0006.8 = 6.8 16. c) 5007 = No 0's may be omitted! 16. d) 009 = 9 e) .009 No 0's may be omitted! 16. f) 00.09 = .09 16. g) 8000 = No 0's may be omitted! h) 8.000 = 8 16. i) 305.002 = No 0's may be omitted! 16. j) 0201.00010 = 201.0001 17. Rewrite each of the following with three decimal digits. Do not 17. a) 12 = 12.000 b) 285 = 285.000 c) 1.2 = 1.200 17. d) .08 = .080 e) 0.5 = 0.500 f) 3.120000 = 3.120 18. Comparing decimals.
