No, they could not. Irrational Numbers are also decimal numbers.
What else can I help you with?
What can you conclude about rational numbers with denominators that are prime?
There is nothing that you can conclude.They could be recurring decimals or terminating decimals [as rational numbers, there is no other form].They may or may not be in their simplified or reduced form: for example 14/7 is a rational number with a prime denominator but it can be simplified.
Is a decimal an irrational or rational number?
A decimal can be both rational and irrational. Rational decimals are 0.25 , 0.234234234..., because they can be converted to a fraction. However, irrational decimals , such as pi = 3.141592.... cannot be converted to a equal fraction. A rational decimal are where the digits regularly repeat, and go to infinity, such as 0.234234234... However, irrational decimals, such as pi = 3.141592... were the digits go to infinity but there is no regular repetition of the numbers. Some other irrational decimals are the square roots of prime numbers. ;_ sqrt(2) = 1.414213562... sqrt(3) = 1.732050808... sqrt(5) = 2.236067978....
If a number isn't a integer what is it?
It is a non-integer. It can be a rational fraction (in decimal or rational form); it can be an irrational number (including transcendental numbers); it could be a complex number or a quaternion.
Could negative mixed numbers be rational numbers?
Not only could they be, but they always are.
When and why do you need decimals?
You need decimals when you measure and fractions. You need decimals, because to measure and fractions. Also, so whole numbers could exist if there are decimals. There will be no math if there's no decimals.
What is the meaning of common decimals?
The common decimals could be the familiar numbers we see most often such as 0.1, 0.5, 0.2 etc.
A real number that is not rational?
Real numbers are any numbers that could be on a number line. Rational numbers are numbers that can be expressed as fractions. Real irrational numbers are things like pi or the square root of 2.
Do integers numbers have decimals?
No, integers are whole numbers that do not have any decimal or fractional parts. Integers include positive numbers, negative numbers, and zero. Decimals are used to represent numbers that fall between integers on the number line.
Why rational numbers were required?
First of all counting numbers (positive integers) are rational numbers so without rational numbers there would be no counting. You could not equitably share one item between two or more people without fractions (rational numbers). Everything does not come in whole numbers - there are times when you need half-a-day, or 2.5 teaspoons, etc.
Is the difference of any two irrational numbers rational or irrational?
It could be either.
Is 18 rational or irrational?

Could you use decimals in a factor tree?
No. Factors of integers are also integers (whole numbers).
