5 = 5/1 is a rational number
As a number which can be expressed as a fraction, 1/2 is a rational number.
Yes, -1/2 is a rational number
One-half is rational because it can be expressed as a quotient of two integers (one divided by two).
No, one half which is 1/2 is not a integer. Its a rational number.
It is 8/6.
Every irrational number is NOT a rational number. For example, sqrt(2) is irrational but not rational. A natural number is a counting number or a whole number, such as 1, 2, 3, etc. A rational number is one that can be expressed as a ratio of two whole numbers, which may be positive or negative. So, -2 is a rational number but not a counting number (it is an integer, though). Also, 2/3 is a rational number but not a whole, counting number or a natural number.
No, 4/3 is 1.333333... which is not a natural number. However, any natural number divided by a natural number will always be a rational number. This is due to the definition of a rational number as being able to be expressed as p/q where p and q are integers. Thus, numbers where p and q are natural numbers represent a subset of all the rational numbers.
The number -1/2 is a rational number, a negative integer divided by a positive integer.
1.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
