It's number 15.\n\nBy definition, a composite number is a positive integer  which is not prime (i.e., which has factors other than 1 and itself). \n\nTherefore, the first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... They're the numbers with factors other than one and itself. \n\n2, 3, 5, 7, 11, 13, ... are not included in the set because their factors are limited to only the number 1 and theirselves. That's why they are prime numbers.\n\nNote that by strict interpretation, it's impossible to determine the highest composite numbers since there are an infinite number of composite numbers. I just started from the smallest composite number and counted eight slots upwards.\n\nAlso note that the number 1 is a special case which is considered to be neither composite nor prime. That's why I haven't included 1 in the 8th.

Writing 1.25 as 1¼, which means 1 and a quarter, is called a mixed number.\n1¼ = 1 + ¼\n\nThis is generally bad notation to use in algebra, because every other time a number, pronumeral or expression is next to another it means multiplication. eg...\n\n2x = 2 * x\n2(2 + x) = 2 * (2 + x)\n4! = 4.3.2.1 = 4 * 3 * 2 * 1\n\nA better way to write mixed numbers is as improper fractions, where the numerator (top number) is greater than the denominator (bottom number). eg...\n\n3¼ = 3 + 1/4 = 12/4 + 1/4 = 13/4\n\nThis way, there is no ambiguity.

I'm not sure I understand your question - do you mean adding odd numbers only to odd numbers and even numbers only to even numbers?  For odd I think it would be the numbers that end in (3 and 7) (1 and 9) and (5 and 5) where they add up to 50, and for the evens the numbers ending in (2 and 8) (4 and 6) that add up to 50.

remember 30 is the numberator (top) and actually has the known "1" as the denominator (bottom).  so multiply 30/1 X 1/7 = 30/7 [because 30 x 1 = 30 and 1 x 7 = 7].  that's the mixed fraction.  you can take it a step further and calculate the fraction:  30 divided by 7.  then you'll get 4.2857.

I can't see the rest of your question, but even numbers can be multiples of three. Like 6 (2x3). They are not mutually exclusive.

You can pick any you feel comfortable with.  "Mixed" is often an option on questionaires, etc where you have to fill that out. \n\nI am sure you are just lovely- don't be labled by anyone.  We're all a mix of cultures.  Talk to your parents about your struggle, they can help.

There are 3 pairs:\n\n1. 0 and 0\n2. 2 and 2\n3. 9 and 9\n\nThere won't be any more as the number values get larger. This is because when the no.s are multiplied, there would be more digits than when the no.s are added. So they can't be opposite if they have diff. no. of digits.

sixteen hundred nine, two thousand nine, two thousand twenty, two thousand, and 19 hundred. Is this what you mean?

Those are mixed numbers containing whole number and a fraction.\n8 1/2=8+1/2=8.5\nSimilarly 1 1/4=1+1/4=1.25 and others.

All of the numbers you have listed are whole numbers, since whole numbers consist of the natural numbers (1,2,3...) and 0. Radical 64 is merely 8 and radical 100 is 10.

very good question: "number" is the quantity in itself: it's "how much you have" of something.\n\nFigures are signs that you use to represent that quantity.\n\nThe number is an objective and absolute entity; the figures you use to represent the number may depend.\n\nfor exemple, if you want to describe the number of x's in the following:\n\nx  x  x  x  x  x  x  x  x  x\n\naccording to the number system you use, the same number can be written 10 (base 10) or A (base 16) or 1010 (base 2). \n\nSo the figures change, but the number is always the same.\n\n---\nAnother thing to think about: consider even numbers.\nThe correct definition of an even number is that it is divisible in two equal parts; if you base your definition on figures, saying that an even number is a number which ends by 0,2,4,6 or 8, you're just referring to base 10 and are not telling the truth relating to other bases:\n\nfor exemple, the number four is written 11 in base 3, but it is still an even number!\nThe same for each odd base: the even number consecutive to the base is always written 11 in that base...\n\nSo to be even is an intrinsic quality of the number; to be written "evenly" according to base 10 criteria is not.

A decimal number is one made out the normal digits 1234567890. A binary number is made out 1's and 0's for example in binary 1=1 10=2 11=3 100=4 101=5 etc

How mixed? I'm mixed too

It's been awhile but  100?  63?  I don't remember what a composite number is so I can't even guess there.
