\n" ); document.write( "\n" ); document.write( "my answers are shown below:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1. is negative5 over 6 a whole natural integer irrational rational or real number?
\n" ); document.write( "i believe this is rational because it is a ratio of two integers.
\n" ); document.write( "2.is 39.99 a whole natural integer irrational rational or real number?
\n" ); document.write( "this is a rational number since it can be expressed as a ratio of two integers. the fractional equivalent would be 3999/100.
\n" ); document.write( "3.square root of 5 a whole natural integer irrational rational or real number?
\n" ); document.write( "square root of 5 is an irrational number because it cannot be expressed as a ratio of two integers other than 5 divided by 1. division by 1 doesn't count.
\n" ); document.write( "4.-80 a whole natural integer irrational rational or real number?
\n" ); document.write( "-80 is an integer. it not a whole number or a natural number because neither of those can be negative.
\n" ); document.write( "5.12 over 3 a whole natural integer irrational rational or real number?
\n" ); document.write( "this is actually a rational number because 5.12 can be expressed as a ratio of two integers and that divided by 3 can also be expressed as a ratio of integers.\
\n" ); document.write( "5.12 = 125 / 25 and (128 / 25) / 3 equals 125 / 75.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "definition of a natural number:
\n" ); document.write( "a positive integer or zero.
\n" ); document.write( "some definitions do not include 0.
\n" ); document.write( "other do, such as this one.
\n" ); document.write( " \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "definition of a whole number:
\n" ); document.write( "Also called counting number. one of the positive integers or zero; any of the numbers (0, 1, 2, 3, …).\r
\n" ); document.write( "\n" ); document.write( "here's another definition that does not include 0 in the set of natural numbers.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Natural numbers: the counting numbers {1, 2, 3, .... }
\n" ); document.write( "Whole numbers: zero, plus the counting number
\n" ); document.write( "{0, 1, 2, 3, ... }
\n" ); document.write( "Integers: the negative and positive whole numbers
\n" ); document.write( "{... -3, -2, -1, 0, 1, 2, 3, ... }
\n" ); document.write( "Rational numbers: Numbers of the form m/n, where m and n are integers and n is non-zero. (Note: All whole numbers are rational numbers because they can be expressed as themselves over 1, i.e. 5 = 5/1, 0 = 0/1, 1003 = 1003/1)
\n" ); document.write( "Irrational numbers: Numbers which are not rational, and whose decimal representation neither terminates nor repeats (example: PI, sqrt(2) ).
\n" ); document.write( "Real numbers: The set of all rational and irrational numbers.
\n" ); document.write( "Complex numbers: For i^2 = sqrt(-1), all numbers of the form
\n" ); document.write( "a + bi, where a and b are real numbers.\r
\n" ); document.write( "\n" ); document.write( "All natural numbers are whole numbers.
\n" ); document.write( "All whole numbers are integers.
\n" ); document.write( "All integers are rational numbers.
\n" ); document.write( "All rational numbers are real numbers.
\n" ); document.write( "All irrational numbers are real numbers.
\n" ); document.write( "All real numbers are complex numbers (i.e. can be expressed as \"a + 0i\".\r
