Rational numbers are numbers that do not have an infinite value. This means that they are not infinite when in decimal form.
Some rational numbers might be infinite but they will always be repeating. For instance, 0.333333333333... is a rational number because the 3 keeps repeating.
The product of 12 x the square root of 11 is infinite and so is not a rational number.
13 multiplied by π is also infinite.
15 x 4.398671.... is not infinite and takes the value of 65.980065 so this is a rational number.
