2. Выполните вычитание:
а)
\[10\frac{3}{4} - 9 = 10 + \frac{3}{4} - 9 = 1 + \frac{3}{4} = 1\frac{3}{4}\]
б)
\[4\frac{3}{17} - 3\frac{2}{17} = (4 - 3) + (\frac{3}{17} - \frac{2}{17}) = 1 + \frac{3-2}{17} = 1 + \frac{1}{17} = 1\frac{1}{17}\]
в)
\[35\frac{3}{67} - 35\frac{2}{67} = (35 - 35) + (\frac{3}{67} - \frac{2}{67}) = 0 + \frac{3-2}{67} = \frac{1}{67}\]
г)
\[56\frac{23}{87} - 43\frac{25}{87} = (56 - 43) + (\frac{23}{87} - \frac{25}{87}) = 13 + \frac{23-25}{87} = 13 - \frac{2}{87} = 12 + 1 - \frac{2}{87} = 12 + \frac{87}{87} - \frac{2}{87} = 12 + \frac{87-2}{87} = 12\frac{85}{87}\]
Ответ: а) \[1\frac{3}{4}\]; б) \[1\frac{1}{17}\]; в) \(\frac{1}{67}\); г) \[12\frac{85}{87}\]
