What are rational numbers and how are they used?
A rational number is a number that can be written in the form a/b, where "a" and "b" are integers and b is not equal to zero. For example, whole numbers are rational numbers.
Is the difference between whole numbers always a whole number?
Difference of two whole number is not always a whole number.For any two whole numbers a & b, a - b = whole number only when a is greater than or equal to b.* * * * *Wrong!Even if a is less than b, the difference is still a whole number. Whole numbers can be negative.So the correct answer to the question is "YES".
Why do whole numbers need an extension?
The first need arose when it was found that the set of whole numbers was not closed under division. That is, given whole numbers A and B (B non-zero), that, in general, A/B was not a whole number - but a fraction.
What are rational numbers that are not integars?
Integers are whole numbers, with no fraction or decimal part. Rational numbers are numbers that can be expressed in the form a/b where a and b are both integers. Thus 1/2 is a rational number, but not an integer. 0.34343434... is a rational number (as it can be expressed as 34/99) but is not an integer.
What is the standar form of a whole number?
The standard form for a number is a way of representing numbers, usually very large or very small, in the form a*10b where 1 <= |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent.

Are whole numbers a rational number?
Yes. A rational number is one that you can write as a fraction a/b, with integers a and b (b not equal to zero). For a whole number, set b = 1. For example, 5 = 5/1, so it is a rational number.
Can a improper fraction be a rational number?
Yes. An improper fraction is defined as a fraction of the form a/b where a > b. This is still the ratio of two whole numbers which is what a rational number is.
In mathematics what is a rational number?
Any number that can be expressed as a ratio of two integers ( whole numbers) providing the second number is not zero. In symbols a number that can be put in the form a/b where a and b are integers ,and b does not equal zero
Is 1.8 is a Rational Number?
Yes. 1.8 = 14/5 = 9/5 which is of the form a/b with a and b integers (whole numbers) so it is rational.

Is 20 irrational?
20 is not irrational because it can be represented in the form a/b, where a and b are whole numbers and b is not 0.
Is a complex number a number that can be written in the form a plus bi where a and b are real numbers?
Yes, a+bi is standard form for a complex number. The numbers (a) and (b) are both real and i is √(-1)
What is a number that can be written in the form a plus bi where a and b are real numbers?
A number of the form (a + bi) is a complex number.
