A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.
The number 8 is a rational number because it can be written as the fraction 8/1.
Likewise, 3/4 is a rational number because it can be written as a fraction.
Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.
Every whole number is a rational number, because any whole number can be written as a fraction. For example, 4 can be written as 4/1, 65 can be written as 65/1, and 3,867 can be written as 3,867/1.
All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction.
An irrational number has endless non-repeating digits to the right of the decimal point. Here are some irrational numbers:
π = 3.141592…
Although irrational numbers are not often used in daily life, they do exist on the number line. In fact, between 0 and 1 on the number line, there are an infinite number of irrational numbers!
1.) The word rational comes from"ratio". A rational number is a ratio of integers. By that I mean that any rational number can be written as:
a/b where a and b are integers and b is not equal to zero.
2.) Rational numbers are numbers that can be expressed as a ratio of two integers. They can be in fraction, decimal or whole number form.
3.) Irrational numbers are real numbers that are NOT rational.
4.)Irrational numbers are numbers that cannot be expressed as a ratio of two integers.
A rational number is defined to be a number that can be expressed as the ratio of two integers.
An irrational number is any real number that is not rational.
A rational number is a number that can be expressed as a fraction. An irrational number is one that can not.
Okay, between your examples and my examples I think Ik enough. Thank you!
