What is an example of a rational number that is a whole number?
Every whole number is a rational number: for example, 3=31. So it is rational. Every whole number n can be written as a fraction of integers: n=n1. We aren’t required to write it that way; we just need to know that it is possible to express every whole number as a fraction of integers, and hence it is rational.
Is a rational number sometimes a whole number?
If a number is a whole number, for instance, it must also be an integer and a rational. If a number is an integer, it must also be a rational.
What is an example of a rational number that is not a whole number?

Is 15 a whole number and a rational number?
Answer. 15 is a rational number because it can be expressed as the quotient of two integers: 15 ÷ 1.
Is a irrational number a whole number?
Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers. This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as the ratio of two whole numbers.
Are there rational numbers that are not whole numbers?
Answer: False A rational number is any number that can be expressed as a fraction. Whereas, a whole number is a positive number without a decimal or fractions. Every rational number is may or may not be a whole number.
Is 1 3 a rational number but not an integer?
where a and b are integers and b=0. Hence 1/3 is rational.
Is pi a real number?
Pi is a number that relates a circle’s circumference to its diameter. Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That’s because pi is what mathematicians call an “infinite decimal” — after the decimal point, the digits go on forever and ever.
Is 3.142857 rational or irrational?
(c) 3.142857 is rational because it is a terminating decimal.

Is 0 A whole number integer or rational number?
Answer: Zero(0) is a rational, whole, integer, and real number.
Is 2/9 rational or irrational?
It is also a real number, as rational numbers are a subset of the real numbers (as are all the others mentioned).
Is 2 a rational number?
2 is a rational number because it satisfies the condition for rational number and can be written in p/q form which is mathematically represented as 2/1, where 1≠0.
What does 3.14 mean in math?
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
