а) 2 \(\frac{3}{7}\) = \(\frac{2*7 + 3}{7}\) = \(\frac{17}{7}\)
6 \(\frac{9}{16}\) = \(\frac{6*16 + 9}{16}\) = \(\frac{105}{16}\)
4 \(\frac{17}{18}\) = \(\frac{4*18 + 17}{18}\) = \(\frac{89}{18}\)
б) Здесь требуется представить в виде неправильной дроби дробную часть, взяв 1 из целой части.
5 \(\frac{3}{8}\) = 4 + 1 + \(\frac{3}{8}\) = 4 + \(\frac{8}{8}\) + \(\frac{3}{8}\) = 4 + \(\frac{11}{8}\)
7 \(\frac{7}{18}\) = 6 + 1 + \(\frac{7}{18}\) = 6 + \(\frac{18}{18}\) + \(\frac{7}{18}\) = 6 + \(\frac{25}{18}\)
3 \(\frac{7}{25}\) = 2 + 1 + \(\frac{7}{25}\) = 2 + \(\frac{25}{25}\) + \(\frac{7}{25}\) = 2 + \(\frac{32}{25}\)
