No, 3 by 0 is not a rational number. A rational number is a number that can be expressed as a fraction, with both the numerator (the number on top) and the denominator (the number on the bottom) being whole numbers.
Since 0 is not a whole number, it is not possible to create a fraction with 0 as a denominator, so 3 by 0 cannot be a rational number.

What type of number is 3 over 0?
3 over 0 is undefined, and therefore not a type of number. In mathematics, a number is defined as a mathematical object used to count, measure, and label. Because 3 over 0 cannot be used to count, measure, or label, it is not considered a number.
What are not real numbers?
A “not real number” is something that is not a real number in the context of mathematics. The most commonly used not real numbers are imaginary numbers, complex numbers, and transcendental numbers.
Imaginary numbers are the square root of negative numbers and cannot be written as a real number multiplied by itself. Instead imaginary numbers are expressed in terms of the imaginary unit (i), which is equal to the square root of -1.
Examples of imaginary numbers include i and 4i.
Complex numbers are all numbers in the form a+bi where a and b are real numbers and i is the imaginary unit. Some examples of complex numbers are 3+2i and -8+6i.
Transcendental numbers are numbers that are not the root of any polynomial equation over the real numbers. These numbers are generally irrational (cannot be written as a ratio of two integers) and can never be written exactly as a decimal; they are always non-repeating and non-terminating.
Some examples of transcendental numbers include pi (π), e, and the golden ratio (φ).
What is 3 over 0 as a fraction?
3 over 0 is undefined as a fraction because you cannot divide by 0. Mathematically, any number divided by 0 is undefined. When dealing with fractions, the denominator (the bottom number) cannot be zero.
What is it called when a fraction is over 0?
A fraction that is over 0 is known as a positive fraction. A positive fraction is a fraction where the numerator (the number on the top of the fraction) is greater than the denominator (the number on the bottom of the fraction), creating a value that is greater than zero.
For example, the fraction 5/4 is a positive fraction, because 5 is greater than 4, resulting in a value that is greater than 0. Another example is 3/2, where again, the numerator (3) is greater than the denominator (2), resulting in a fraction that is over 0, or a positive fraction.
Is 3 negative a positive?
No, 3 negative is not a positive. In mathematics, a negative number is any real number that is less than zero. So 3 negative (-3) is a negative number and not a positive number, which would be a number greater than or equal to zero.
A common mistake people make is to incorrectly refer to 3 negative (-3) as a positive, but this is not the case, since a negative number cannot be considered a positive number.
How do you know if a number is irrational?
In order to determine whether a number is irrational or not, it is first necessary to understand what qualifies a number as irrational. Generally, an irrational number is a number that cannot be expressed as a fraction, or in other words, a number that cannot be written as a ratio between two whole numbers.
Irrational numbers also cannot be expressed as terminating or repeating decimals, since it would imply that the number could be written as a fraction.
Some of the most commonly known examples of irrational numbers include pi (π), the square root of 2, and e (Euler’s constant). To confirm that a number is irrational, you can attempt to express it as a fraction.
If it can be expressed that way, the number is rational; if not, it’s irrational. You can also use a scientific calculator to approximate the number and check its decimal representation to see if it contains a repeating pattern or if it terminates.
If it doesn’t, the number is likely irrational.
