Answer 2

$200,75t-81\frac{5}{14} k+80\frac{2}{21}k-199\frac{1}{3}t=(200\frac{3}{4}t-199\frac{1}{3}t)-(81\frac{5}{14}k-80\frac{2}{21}k)=[(200-199)+(\frac{3}{4}-\frac{1}{3})]t+[(81-80)+(\frac{5}{14}-\frac{2}{21})]k=(1+\frac{9-4}{12})t-(1+\frac{15-4}{42})k=1\frac{5}{12}t+1\frac{1}{42}k\\\\Otvet:\boxed{1\frac{5}{12}t-1\frac{11}{42}k}$
