д) 2\(\frac{3}{4}\) * (4\(\frac{1}{2}\) : 6\(\frac{3}{4}\)) = \(\frac{11}{4}\) * (\(\frac{9}{2}\) : \(\frac{27}{4}\)) = \(\frac{11}{4}\) * (\(\frac{9}{2}\) * \(\frac{4}{27}\)) = \(\frac{11}{4}\) * (\(\frac{9*4}{2*27}\)) = \(\frac{11}{4}\) * (\(\frac{36}{54}\)) = \(\frac{11}{4}\) * (\(\frac{2}{3}\)) = \(\frac{11*2}{4*3}\) = \(\frac{22}{12}\) = \(\frac{11}{6}\) = 1\(\frac{5}{6}\)

Ответ: 1\(\frac{5}{6}\)
