15. In our system of numbering, what is the function of 0?

16. 0's on the right of a decimal, or on the left of a whole number, do not add
16. anything to the value.

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 places. Do not
17. change the value.

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. Arrange these from smallest to largest.

19. a) Which number is the smallest: .0059 .0201 .018 ? .0059

19. b) Which is the largest? .0201

20. Which number is largest: 6.4 6.388 6.41 ? 6.41

21. Which number is largest: 0.001 0.00102 0.0011 ? 0.0011

22. Which number is smallest: .0631 .063 .2 .063
