Every number of the form 0.0k((0n)1) ∗ is the product of a number of the previous type and the rational number 10 − k, and so is rational.

WebA Rational Number can be made by dividing an integer by an integer. (An integer itself has no fractional part.) Example: 1.5 is a rational number because 1.5 = 3/2 (3 and 2 are both … WebIf the square root of our prime number p is rational, that means we can say √p = a/b, where a and b are integers - recall rule/property #3. From rule/property #4 we know we can reduce the fraction a/b if it is not already in reduced form. Now you might say “what if a/b is not reduced?” That’s OK – we can reduce it and call it c/d.
