a) 13 \(\frac{8}{9}\) - 4 = 9 \(\frac{8}{9}\)
б) 17 \(\frac{5}{14}\) - 5 \(\frac{3}{14}\) = 12 \(\frac{2}{14}\) = 12 \(\frac{1}{7}\)
в) 9 \(\frac{5}{7}\) - 3 \(\frac{6}{7}\) = 8 \(\frac{12}{7}\) - 3 \(\frac{6}{7}\) = 5 \(\frac{6}{7}\)
г) 100 - 20 \(\frac{3}{14}\) = 99 \(\frac{14}{14}\) - 20 \(\frac{3}{14}\) = 79 \(\frac{11}{14}\)
а) 6 + 8 \(\frac{7}{13}\) = 14 \(\frac{7}{13}\)
б) 12 + 19 \(\frac{5}{24}\) = 31 \(\frac{5}{24}\)
в) 5 \(\frac{7}{15}\) + 8 \(\frac{4}{15}\) = 13 \(\frac{11}{15}\)
г) 13 \(\frac{5}{101}\) + 7 \(\frac{25}{101}\) = 20 \(\frac{30}{101}\)
д) 4 \(\frac{3}{7}\) + 15 \(\frac{4}{7}\) = 19 \(\frac{7}{7}\) = 20
е) 3 \(\frac{9}{13}\) + 4 \(\frac{8}{13}\) = 7 \(\frac{17}{13}\) = 8 \(\frac{4}{13}\)
