Is 1.234 is a not rational number?
First of all , do not use the phrase ' not rational' . The word in the English language, and mathematics is 'IRRATIONAL'. Net 1.234 is rational; it can be converted to a ratio(fraction). For irrational numbers the decimals go to inifinity and there is no regular order in the decimal digits. 'pi' is probably the most well known irrational numbers at pi = 3.141592654... The three terminl dots/stops indicate to mathemticians, that the number goes to infinity. Notice also, there is no regular order of digits in the decimal moiety. Since the number given ends at '4' , then it does not go to infinity, hernce it is rational . To convert to a ratio (fraction) 1.234 = 1 234/1000 Cancel down by '2' 1 117/500 (THis is the fraction in its lowest terms).
What is the nth term of -2 -8 -18 -32 - 50?
The nth term is 2n2. (One way to find that is to notice at all the numbers are even, then divide them by 2. The sequence becomes 1, 4, 9, 16, 25, which are the square numbers in order.)
How many prime numbers are there upto 10 20 30 40 50 and so on what will you notice?
Well, you can look it up yourself in a table of prime numbers. But the general tendency is that, the higher you go, the less prime numbers you'll find in each interval. The long-term tendency is that among the first "n" numbers, you'll find n / ln(n) prime numbers, where ln(n) is the natural logarithm. This formula is not terribly accurate for small numbers, but it gets better and better as "n" gets larger.
How do you notice that it is factors or prime or composite numbers?
First of all, every number is a factor - of its multiples.There is no general way to distinguish between prime and composite numbers. At one level, though, there are some simple ways. If the number is not 2, but ends in 0, 2, 4, 6 or 8 then it is a composite, If the number is not 5 but ends in 0 or 5 it is composite. If the number is not 3 but the sum of all the digits of a number is 3 or divisible by 3, then it is composite. There are moderately complicated divisibility rules for 7 and 11. But this method does not identify all composite numbers and there is no guaranteed method.
Determine the number of integers between 1 to 250 that are divisible by any of the integer 3 or 5 or 7?
It would probably be easier to say that all numbers between 2 and 250 with the exception of the numbers 121, 143, 169 are divisible by the numbers 2,3,5, or 7. Explanation: One of the basic rules of math called the "Fundamental theorem of arithmetic" states that all numbers can be written as a product of prime numbers. 2, 3, 5, and 7 are the first four prime numbers. We also know that at least one of the numbers multiplied has to be less then 16. This is because the square root of 250 is about 15.81. If more then one of the numbers were larger then 16, then the result would be greater then 250. Example = 16*16 = 256. So now we know that all numbers between 2 and 250 are divisible by prime numbers that are less then 16. These numbers are "2,3,5,7,11,13." If you notice the first four numbers in that list are the numbers that you gave. This means that the only numbers between 2 and 250 that aren't divisible by 2, 3, 5, and 7 are the numbers (11*11), (11*13), and (13*13) or 121, 143, 169.
What is the relationship of a fraction to a ratio?
Fractions and ratios are practically the same thing. Fractions are rational numbers (notice the word "ratio" at the beginning of "rational"). They are sometimes used in slightly different contexts, but both express parts of a whole.
Is every rational number a fraction?
Every fraction is a rational number, but not every rational number is a fraction.A fraction is a number that expresses part of a whole as a quotient of integers (where the denominator is not zero).*A rational number is a number that can be expressed as a quotient of integers (where the denominator is not zero), or as a repeating or terminating decimal. Every fraction fits the first part of that definition. Therefore, every fraction is a rational number.Both 22/7 and 1/3 are fractions, therefore they are both rational numbers. They also are repeating decimals, as 22/7 = 3.142857142857142857... (notice that the 142857 repeats) and as 1/3 = .333...An irrational number, on the other hand, neither terminates nor repeats.(The confusion about 22/7 may come because that fraction is often used to represent the number pi. It is not the number pi, just an approximation. The number pi is a decimal that begins 3.1415... and continues on without terminating or repeating. )But even though every fraction is a rational number, not every rational number is a fraction. Basically because rational numbers do not have to express a part of a whole. It can express a whole, as in an integer. And an integer is not a fraction.

What are the difference between rational to irrational?
Rational numbers are numbers that can be expressed as a fraction of two integers. For example, 2/3, 8/27, and 4/1 are all rational numbers. In decimal form, those three numbers would be written as .66666666666... (I'm using the "..." to represent the fact that those 6's after the decimal point continue on forever), .296296296296296..., and 4, respectively. Notice how those three numbers, when written in decimal form, either repeat some pattern after their decimal point, or end. This is, in fact, the case for every rational number; they either terminate, or they have an infinite amount of some repeating number or group of numbers after their decimal point.Irrational numbers differ from rational numbers in that none of the above apply; i.e., they can't be expressed as a fraction of two integers, they don't repeat indefinitely, and they don't end. A couple of famous examples of irrational numbers are pi and the square root of two.

What do you notice about the numbers that can be evenly divided by 2?
there even and they are mostly composite numbers
What do you notice about the locations of the prime numbers greater than 3?
If you notice something, it is [most likely] a false impression. There is no known pattern to prime numbers.
