Question

-6, -2/5, 0, 0.5,7.7, sq rt of 5 and sq rt of 36

List the Natural Numbers,Whole Numbers,Intergers, Rational Numbers,Irrational Numbers, and Real Numbers

Answer 1

irrational are all the square rooted numbers.
real numbers are all the whole numbers
rational numbers are all numbers that are not decimals or square roots :)

Answer 2

Does that make sense?

Answer 3

oh I forgot some of them xD
whole numbers exclude all decimals and square rooted numbers as well. Natural numbers are all whole numbers

Answer 4

so Irrational would be sq rt of 5 and 36
rational number -6,-2/5, 0
Whole numbers -6,0
Natural numbers -6,0 ??

Answer 5

-2/5 is irrational

Answer 6

okay and would sq root of 36 be a whole number because if you take the root it would be 6?

Answer 7

whole numbers / natural numbers are only positive as well (whole numbers include 0) Integers are the set of all whole numbers and their opposites (negatives)

Answer 8

Yes, sq root of 36 is a whole number.

Answer 9

would -6 still be said a whole number

Answer 10

The sets of numbers:
Natural: The set of the 'purest' numbers. {1, 2, 3, ... }
Whole: The set of all natural numbers and including 0. {0, 1, 2, 3, ...}
Integers: The set of all natural numbers, their opposites, and zero. {... -3, -2, -1, 0, 1, 2, 3, ...}
Rational: All numbers that may be expressed in the form A/B, where A and B are integers.
Irrational: All numbers that cannot be expressed in the form A/B. (nonterminating decimals, square roots of numbers that are not perfect squares, etc.)

Real: The set of all rational and irrational numbers together.



-6 is in the integers group. It is not a whole number or a natural number.
