Answer 1

$frac{(6-4,5)}{0.003} =frac{1,5}{0.003} =500$

$frac{frac{5}{6}-frac{7}{3}cdot0.2}{1frac{5}{6}}=frac{frac{5}{6}-frac{1.4}{3}}{frac{11}{6}}=frac{frac{5}{6}-frac{2.8}{6}}{frac{11}{6}}=frac{frac{2.2}{6}}{frac{11}{6}}=frac{2.2}{11}=0.2$

$10sqrt{3}-sqrt{48}-sqrt{75}=10sqrt{3}-4sqrt{3}-5sqrt{3}=sqrt{3}$

$(81^frac{1}{4}-64^frac{1}{6}):121^frac{1}{2}=(sqrt[4]{81}-sqrt[6]{64}):sqrt{121}=(3-2):11=frac{1}{11}$

$5,6a+8.4a+186.4=14a+186.4=14cdot3.5+186.4=49+186.4=235.4$
