What is an easy way to define rational?
The answer is rational when you divide one whole number by another one.
Is negative zero point two a rational or irrational number?
-0.2 is another way of saying -1/5. It's rational.
Is 40.16 rational?
All rational numbers can be expressed as one whole number over another whole number. 40.16 = 4016/100 = 1004/25 1004 is a whole number, 25 is a whole number, which means 1004/25, another way of writing 40.16, is one whole number over another whole number; → Yes, 40.16 is a rational number
Is the number 3.122333444455555 rational or irrational?
It is rational, since it can be written as one whole number divided by another whole number. For example, it can be written as: 3122333444455555/1000000000000000. A somewhat laborious way to write a number, but it can be done.
Which way of writing the number can be used to show that it is a rational number?
If it can be expressed as a fraction then it is a rational number
Why does a rational number plus a rational number or a rational number multiplied by a rational number equal to rational number?
The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.
Is 3.40764076407640764076 an rational number or irrational?
As a terminating decimal 3.40764076407640764076 = 340764076407640764076/100000000000000000000 which is a rational number As an approximation to the recurring decimal 3.4076... = 34073/9999 which is a rational number. So either way, it is a rational number.
Is 3.5 a rational number or an irrational number?
It is a rational number. One way this can be proved is that it can be represented as a fraction: 7/2.
What is the sum if you multiply two rational numbers?
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
Is pi rational?
A rational number is a number that can be expressed as one integer divided by another. Decimals can only be expressed in such a way if they are repeating. For example 0.4646464646... is 46/99 and 0.333333.... is 1/3. Because pi is a non repeating decimal, it cannot be expressed in this way. Thus it is an irrational number.
How is an irrational number different from rational numbers?
Irrationals differ from Rationals by definition. If a real number is not a Rational Number then it is Irrational. One way to find out if a number is either Rational or Irrational is to look at its decimal value. If the digits past the decimal point terminate then it is a Rational number. If the digits past the decimal point repeat the same digit forever, of if it repeats a sequence of digits over and over, then it is a Rational Number. If the digits past the decimal point do not repeat in any pattern, and do not stop, then it is an Irrational number. Another way to find out if a number is Rational or Irrational is if it can be exactly described by a fraction (ratio). If it is the same as some fraction, then it is a Rational Number. Irrationals cannot be exactly described as a fraction.
What numbers are rational numbers?
A rational number is any number that can be made by dividing one integer by another.0.5 is a rational number as it can be made by dividing the number 1 by the number 22 is a rational number because it can be made by dividing 2 by 1-6.6 is a rational number because it can be made by dividing -66 by 10---------------------------------------------------------Note there are number that are called irrational numbers. Irrational numbers are all "real" numbers (numbers with a decimal point) that cannot be written as a simple fraction - the decimal goes on forever without repeating.For instance the number Pi is an irrational number.A rational number is a real number that can be expressed as a ratio of two integers. Another way to think about it is this: if you can write a number as a fraction then it's a rational number.
