Ответ
\(\frac{12}{25}\) · \(\frac{1827}{500}\) = (12 · 1827)/(25 · 500) = \(\frac{5481}{3125}\).
\(\frac{2587}{1000}\) · \(\frac{327}{1000}\) = (2587 · 327)/(1000 · 1000) = \(\frac{845949}{1000000}\).
\(\frac{5481}{3125}\) − \(\frac{845949}{1000000}\) = \(\frac{1753920}{1000000}\) − \(\frac{845949}{1000000}\) = \(\frac{907971}{1000000}\).
(\(\frac{2548}{125}\)) : (\(\frac{208}{25}\)) = \(\frac{49}{20}\).
\(\frac{907971}{1000000}\) + \(\frac{49}{20}\) = \(\frac{907971}{1000000}\) + \(\frac{2450000}{1000000}\) = \(\frac{3357971}{1000000}\).
Ответ: 3,357971.
