A rational number is any number that can be written as a ratio, or fraction, of 2 whole numbers.
There is no such thing as the ratio of a number. You need two numbers to calculate a ratio. A ratio is the same as a quotient. For example, the ratio of 4 to 2 is the same as 4 divided by 2.
No, some numbers, eg sqrt 2, are irrational, which means they cannot be written as a ratio between two whole numbers. Some numbers are also transcendental, but you don't want to go there!
Rational numbers.
An irrational number is a number that cannot be written as a ratio of two whole numbers. That is, there are no two integers, X and Y (with Y>0) such that the number can be written as X/Y. Sqrt(2), pi, log(3) are examples of irrational numbers.
A rational number is any number that can be written as a ratio, or fraction, of 2 whole numbers.
Some examples are an irrational number, an imaginary number, a complex number.
1:2 is a ratio
1.5 is a rational number because it can be written as the ratio 3/2 7 is a rational number because it could be written as the ratio 7/1 3/4 is a rational number because it could be written as a fraction
A number that can be written as a ratio is called a rational number. Some examples are 1/2, 2/3 3/1 (which is 3), and 1/1000000. Some examples of numbers that cannot are the constant Pi and the e, the base of natural logs.
There is no such thing as the ratio of a number. You need two numbers to calculate a ratio. A ratio is the same as a quotient. For example, the ratio of 4 to 2 is the same as 4 divided by 2.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. The ratio is exactly 1:1.
