Question: Nucleus A has a half-life that is twice that of nucleus B. At t = 0 the number of B nuclei in a sample is

Nucleus A has a half-life that is twice that of nucleus B. At t = 0 the number of B nuclei in a sample is twice that of A nuclei. If the half-life of A is 1 h, will there ever be an instant when the number of A and B nuclei are equal? If so, when will this moment occur?
