How do you know if a number is rational
WebThe square root of a given number is rational if and only if it is an integer, which is equivalent to the given number being a perfect square. A straightforward way to determine if a number is a perfect square is to derive its prime factorization. It is a perfect square if and only if the exponent of every prime in that factorization is even. WebAnswer (1 of 3): All repeating decimals are rational. A better question might be ‘how do I find the ratio that corresponds to a repeating decimal?’. Examine the number to determine its period. Multiply by ten to the power of that period. Subtract the original number. Divide and optionally reduce...
