1) 9 + \(\frac{3}{17}\) = 9 \(\frac{3}{17}\)
2) \(\frac{9}{72}\) + 5 = \(\frac{1}{8}\) + 5 = 5 \(\frac{1}{8}\)
3) 4 \(\frac{5}{18}\) + 2 \(\frac{4}{18}\) = 6 \(\frac{9}{18}\) = 6 \(\frac{1}{2}\)
4) 6 \(\frac{7}{15}\) - 2 \(\frac{3}{15}\) = 4 \(\frac{4}{15}\)
5) 9 \(\frac{11}{16}\) + 4 \(\frac{3}{16}\) - 2 \(\frac{2}{16}\) = 13 \(\frac{14-2}{16}\) = 11 \(\frac{12}{16}\) = 11 \(\frac{3}{4}\)
6) 15 \(\frac{7}{10}\) + 2 \(\frac{2}{10}\) - 4 \(\frac{1}{10}\) = 17 \(\frac{9-1}{10}\) = 13 \(\frac{8}{10}\) = 13 \(\frac{4}{5}\)
