Robots X, Y, and Z each assemble components at their respective constant rates. If $${r}_{x}$$ is the ratio of Robot X's constant rate to Robot Z's constant rate and $${r}_{y}$$ is the ratio of Robot Y's constant rate to Robot Z's constant rate, is Robot Z's constant rate the greatest of the three?
(1)$${r}_{x}<{r}_{y}$$
(2)$${r}_{y}< 1$$
