Technetium $99$ m $({?}^{99m}Tc)$ is a radioactive nucleus with a half$-$life of $6\mathrm{.}03$ hours. After a ${?}^{99m}Tc$ nucleus emits a gamma ray, it becomes a ${?}^{99}$ Tc nucleus. ${?}^{99}Tc$ is also radioactive, with a halflife of $213000$ years, and it decays into ${?}^{99}Ru.$

$2$ weeks after ${?}^{99m}Tc$ was administered to the patient, what fraction of it is ${?}^{99m}Tc?$ What fraction of it is ${?}^{99}Tc?$ What fraction of it is ${?}^{99}Ru?$
