Can the difference between two rational numbers be irrational?

Yes, the difference of two rational numbers is a rational number.

Is the difference between two rational numbers rational?

The difference between two rational numbers must be a rational number. A rational number is a number that can be written in the form a/b where a is an integer and b is a non-zero integer.

What is the difference between rational and irrational numbers Why does that difference exist?

A ratio of two large numbers such as (129,367,871)/(547,724,863) would also constitute an example of a rational number for the simple reason that both the numerator and the denominator are whole numbers. Conversely, any number that cannot be expressed in the form of a fraction or a ratio is termed as irrational.

How do you find the difference between two rational numbers?

The difference between two rational numbers, a/b and c/d, is equal to the result of subtracting the smaller number from the larger number. To find the difference between rational numbers, or to subtract rational numbers, we use the following formula: a/b – c/d = (ad – bc) / bd.

Irrational numbers are those real numbers that cannot be represented as terminating or repeating decimals.

What numbers are irrational numbers?

Among irrational numbers are the ratio π of a circle’s circumference to its diameter, Euler’s number e, the golden ratio φ, and the square root of two; in fact all square roots of natural numbers, other than of perfect squares, are irrational.

What makes an irrational number irrational?

Definition of Irrational Numbers. A number is said to be irrational when it cannot be simplified to any fraction of an integer (x) and a natural number (y). It can also be understood as a number which is irrational. The decimal expansion of the irrational number is neither finite nor recurring.
