What is the union of integers and rational numbers?
Oh, dude, the union of integers and rational numbers is just all the numbers you can think of, like your whole math squad hanging out together. Integers are like the cool kids with no decimal parts, and rationals are the ones who can't decide if they want to be whole or have a fraction. So, when you put them together, it's just a big math party where everyone's invited.
What are irrational and rational numbers?
Rational numbers are any numbers that can be expressed as a fraction. For example 1/3, 1/2, and 2. Irrational numbers are numbers that can not be expressed as a fraction. Some examples are Pi, the square root of 2, and e. Both rational and irrational numbers are real numbers. Unlike imaginary numbers like the square root of -1.An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.Rational and irrational numbers are both subsets of real numbers, together they make up the set of what we call real numbers.If you have trouble remembering which is which, just think of rational numbers as fractions, or numbers that can be written as a/b where a and b are integers. Remember that b can equal 1 so [2 = 2/1]. Therefore all integers, as well as whole and natural numbers are also rational numbers.Irrational numbers are real numbers that are not rational. One way that people describe Irrational is the answer goes on and on forever and does not have a repeating pattern. Two classic examples are Pi (3.14159...), and the base of the natural log e (2.7128...).Rational, when expressed in decimal form, can stop (terminate) at a certain point or it may have a pattern of digits which repeats forever. An example of a rational that repeats is 1/3. Certainly it is written as a/b with a and b both being integers, but its decimal representation is 0.333.... where in this case the dots mean that the (3) repeats forever.There is a hierarchy of numbers and understanding it sometimes helps remember and understand the differences.At the top of the hierarchy are the complex numbers. Next come the real numbers and then then rational numbers. Next comes the integers, then the whole numbers and last the natural numbers.An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.
Define and give example of rational numbers?
Oh, dude, rational numbers are like any number that can be expressed as a fraction where the numerator and denominator are integers. So, like 3/4, -5/2, and 0 are all rational numbers because you can write them as fractions. It's like the cool kids club of numbers, you know?
What are special kinds of decimals?
There are irrational numbers (like PI and e) that have infinitely many decimals which do not repeat and rational numbers (the quotient of two integers) which do eventually repeat.
What is a ration number?
A rational number is a number that can be expressed as the quotient (i.e. ratio or fraction) of two integers. ( Integers are rational since any integer, n ,can be written as n/1 )Rational numbers are numbers that can be expressed as fractions whereas Irrational Numbers cannot be expressed as fractionsA rational number is a number that terminates or ends. As in a perfect square like: 144; 36; 625 etc.More specifically, a rational number is a number that can be expressed as the ratio of two integers, where the denominator is not zero. 1.37, for instance, is rational because it can be expressed as 137 / 100.It is any whole number even if it's a negative numberAny number that can be expressed as a fraction is a rational number whereas irrational numbers can't be expressed as a fractions.In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number.
