How can decimal repeat in a number? :evil: .I am really cofused. :blush:

yes a repeating decimal is a rational number.for example-3.66666666......
here six is repeating itself infinite times
and another example 2.456745674567456745674567......
here 4567 is repeating itself so it is also a rational number.and it is also called recurring decimal..

hi baby really great to see that at least one person knows about the rational number finally.hehehe.....:)

i was searching for a thread and there i found many threads of my interest and maths topic is also the one.and i have to read all of them for MAT exam.

Friends you all are genius. If you people become maths teacher, student would get big 0.
Baby Angel your answer is correct.

Friends in the previous thread, I have already written about the properties of rational number. -25 is a rational number and also square root of 25. The square root of 25 is +5 and -5. Both the numbers are rational numbers.

The fractional numbers and the repeating numbers are all rational numbers. It may be a possitive or a negative integer.
e.g. 121/324
-333/321.4
0.87999999
5555.9999
43
-687
-4.35/8.9
1.23/-2.3

Friends here is my question. Guess whether the numbers are rational or not?
3333.7689654.....
-0.000076389.....
square root of 3 and 7

I even tried to searc about this.
I think rational number means if we get any remainder when we divide a number with 2 then it is known as rational number. am i right

Number not divisible by 2 is either odd number or prime number. Rational number includes odd numbers and prime numbers. What about even, whole, decimals and fractions? Rational numbers include all except few non repeating decimal numbers and integers.

terminating and recurring(repeating)decimals are rational numbers.
Non-terminating and non-recurring decimals are irrational numbers.

Yes this is known but answer the question that I have mentioned above. I hope you have right answer for my question.

firstly i want to give you the correct definitions of all:
prime numbers-the number other than one which does not have any factor apart from one and itself is called a prime number.Ex-2,3,5,7,11,13 and so on..
here 2 is divisible by 2 so your statement was wrong.

Even numbers:all the numbers which are divisible by 2 are called even numbers.Ex-2,4,6,8,10 and so on.

Odd numbers:numbers that are not divisible by 2 are called odd numbers.Ex-1,3,5,7,9 and so on

Integers:the set of all non-fractional numbers lying between -infinity and +infinity are called integers.they are of two types.
Positive integers:+1 to +infinity.
Negative integers:-1 to -ininity.
0 is neither positive nor negative integer.

Natural numbers:All the positive integers are called natural numbers.ex-1,2,3,4,5 and so on..

Whole numbers:Set of all positive integers and 0 are called whole numbers.Ex-0,1,2,3,4 and so on.

and now coming to your question.yes rational numbers include even numbers,whole numbers,decimals and fractions.
rational numbers not include the numbers which are not repeating decimals or non-terminating decimals like 3.1245679874537.... so it is a non-recurring(non-repeating) and non-terminating decimal.
any more query?

It seems as if you are totally confused with rational and irrational numbers. Have patience and go through it once again. Your first answer was right.

firstly i want to give you the correct definitions of all:
prime numbers-the number other than one which does not have any factor apart from one and itself is called a prime number.Ex-2,3,5,7,11,13 and so on..

Your explanation is wrong. Not only 2, all numbers can be divided by itself and one. Here is the link for list of prime numbers. Check it.

Actually I asked the above question. If you like it then you can solve it for fun.

Very happy to see a Maths scholar in forum....Sanjeev has already forgotten his maths lessons years back. :P

Even me forgotten maths problems now I am depending on calculator to count each and every thing.

Then you need my special maths class....
