describe the set of rational numbers.?

Answer 1

rational numbers are like 1,2,3,4,5,6,7 and so on... and that is a whole set, also like 2,4,6,8,10,12, and so on. Irrational numbers are like 1.2 ,3.5, 6.2, 4.832, 7.8453, and so on. Oh yeah rational numbers can also be negative numbers and positive numbers like -4, -2, 0, 2, 4,

In mathematics, a rational number (commonly called a fraction) is a ratio or quotient of two integers, usually written as the vulgar fraction a/b, where b is not zero.

Each rational number can be written in infinitely many forms, for example 3 / 6 = 2 / 4 = 1 / 2. The simplest form is when a and b have no common divisors, and every non-zero rational number has exactly one simplest form of this type with positive denominator. A fraction in this simplest form is said to be an irreducible fraction, or a fraction in reduced form.

The decimal expansion of a rational number is eventually periodic (in the case of a finite expansion the zeroes which implicitly follow it form the periodic part). The same is true for any other integral base above one, and is also true when rational numbers are considered to be p-adic numbers rather than real numbers. Conversely, if the expansion of a number for one base is periodic, it is periodic for all bases and the number is rational.

A real number which is not a rational number is called an irrational number.

The set of all rational numbers, which constitute a field, is denoted by Q, or in blackboard bold . Using the set-builder notation is defined as such:

Answer 4

a rational number is a number that terminates or stops.

examples:

7 .897 0.45 1/2

not examples:

998786570000-->

when dealing with fractions and you put it in a calculator the easist way to do it is to divide the top by the bottom so u get a decimal.

1/2 is .5 its rational the square root of 81 is 9 its rational and os on

Answer 5

366666 00000 5 1 7 111111
3 6 0 0 8 5 1 5
344444 00000 8 1 5

366666 00000
3 6 0 0
344444 00000

366666 0007 6 6 5555 9999
3 6 0007 6 6 5 6 55
344444 0 0 6666 5553 4444

Answer 6

4) n = 2 (power element) l = 0 (s orbital) ml = 0 ( s orbitals do not have an angular momentum) ms = +a million/2 (spin quantum) This describes the outer power ranges. the interior element will be n=a million l. m l will be a similar. The question did not ask or contain the 1s2 orbital.

Answer 7

rational numbers are numbers that are defined by the fact that they can be written as a ratio of two nunbers ie: 10/3 when you try to descrbe them in the natural number line you can only bracket some of themi as they are repressented then as an infinity (10/3 = 3.33333333......) or as it is also calle an asymptote

Answer 8

the numbers whose treatment and meds have worked. All the others are still committed and irrational--they just can't be dealt with :P

Answer 9

Any whole (positive) number in it's simplest form.

Answer 10

any real number that is not irrational
