The decay constants in two different samples, A and B, of radioactive nuclei are related according to T1/2,B=(1/2)T1/4,A. In a certain period the number of radioactive nuclei in sample A decreases to one-fourth the number present initially. In this same period the number of radioactive nuclei in sample B decreases to a fraction f of the number present initially. Find f, expressed as a decimal.
