Given that $210$ pairs / $6$ days / $7$ workers = $5$ pairs/day per worker, then:

( $5$ pairs/(day * worker))( $10$ days)( $x$ workers) = $450$ pairs $\Rightarrow 50x = 450 \Rightarrow \boxed{x=9}$ workers.

We know 210/6 = 35/7 = 5(our constant of cups(C) that each worker(W) made) same with 450/10 = 45/W = 5(C) so the only number that can fit on the operation is 9.
