∙ 13y agoA rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.

∙ 13y agoThere are many different kinds of fractions, some rational and some irrational.
All integers and fractions are rational numbers whereas an irrational number can't be expressed as an integer or a fraction.
There are infinitely many rational number between 13 and 25. Some examples:13.0000001 13.0000001002 13.0000002
It is a prime number It is a rational number It is an odd number It is 11/1 as an improper fraction It is 11.0 as a decimal
Some real numbers can be expressed as a fraction, others cannot. Those that can be are called rational, and those that can't be are called irrational.
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 rational number is a number that ends at some point. An irrational number is a number that never ends. Basically a fraction that can be simplified is a rational fraction. Pi is an example of an irrational number, because it never ends.

Some real numbers can be expressed as a rational fraction.
Any number that can be expressed as a fraction is rational such as:- 3 = 3/1, 1.25 = 5/4, 0.125 = 1/8, 0.75 = 3/4 .... etc
Just write ANY fraction, with a polynomial in the numerator, and a polynomial in the denominator.

There are an infinite number of rational numbers between 0.26 and 0.29 - some examples are, 0.27, 0.275, 0.28, 0.285

The ancient greek mathematician Pythagorasbelieved that all numbers were rational (could be written as a fraction), but one of his students Hippasus proved (using geometry, it is thought) that you could not represent the square root of 2 as a fraction, and so it was irrational.A rational number is a number that can be written as a simple fraction (i.e. as a ratio).Example 1.5 is a rational number because 1.5 = 3/2(it can be written as a fraction).A rational number is a number that can be in the form p/q where p and q are integers and q is not equal to zero.
