Привет! Сейчас решим эти примеры с дробями. Будь внимателен, и у тебя всё получится!

1) 51 - 1 \(\frac{7}{8}\) = 50 \(\frac{8}{8}\) - 1 \(\frac{7}{8}\) = 49 \(\frac{1}{8}\)

2) 5 \(\frac{5}{4}\) - 2 \(\frac{1}{4}\) = 5 + 1 \(\frac{1}{4}\) - 2 \(\frac{1}{4}\) = 6 \(\frac{1}{4}\) - 2 \(\frac{1}{4}\) = 4

3) 81 \(\frac{2}{14}\) - 63 \(\frac{7}{14}\) = 80 \(\frac{16}{14}\) - 63 \(\frac{7}{14}\) = 17 \(\frac{9}{14}\)

4) 85 \(\frac{2}{4}\) - 71 \(\frac{3}{4}\) = 84 \(\frac{6}{4}\) - 71 \(\frac{3}{4}\) = 13 \(\frac{3}{4}\)

5) 25 - 24 \(\frac{18}{23}\) = 24 \(\frac{23}{23}\) - 24 \(\frac{18}{23}\) = \(\frac{5}{23}\)

6) 8 \(\frac{2}{74}\) - 1 \(\frac{7}{74}\) = 7 \(\frac{76}{74}\) - 1 \(\frac{7}{74}\) = 6 \(\frac{69}{74}\)

7) 15 \(\frac{5}{4}\) - 12 \(\frac{1}{4}\) = 15 + 1 \(\frac{1}{4}\) - 12 \(\frac{1}{4}\) = 16 \(\frac{1}{4}\) - 12 \(\frac{1}{4}\) = 4

8) 11 \(\frac{3}{5}\) - 5 \(\frac{4}{5}\) = 10 \(\frac{8}{5}\) - 5 \(\frac{4}{5}\) = 5 \(\frac{4}{5}\)

9) 3 \(\frac{7}{7}\) - 1 \(\frac{5}{7}\) = 4 - 1 \(\frac{5}{7}\) = 3 \(\frac{2}{7}\)

10) 2 \(\frac{8}{15}\) - 1 \(\frac{9}{15}\) = 1 \(\frac{23}{15}\) - 1 \(\frac{9}{15}\) = \(\frac{14}{15}\)

11) 13 \(\frac{7}{13}\) - 2 \(\frac{5}{13}\) = 11 \(\frac{2}{13}\)

15) 3 \(\frac{2}{17}\) - 1 \(\frac{6}{17}\) = 2 \(\frac{19}{17}\) - 1 \(\frac{6}{17}\) = 1 \(\frac{13}{17}\)

16) 11 \(\frac{8}{11}\) - 3 \(\frac{5}{11}\) = 8 \(\frac{3}{11}\)

17) 13 \(\frac{6}{10}\) - 13 \(\frac{5}{10}\) = \(\frac{1}{10}\)

18) 15 \(\frac{6}{7}\) - 5 \(\frac{3}{7}\) = 10 \(\frac{3}{7}\)

19) 11 \(\frac{3}{5}\) - 5 \(\frac{4}{5}\) = 10 \(\frac{8}{5}\) - 5 \(\frac{4}{5}\) = 5 \(\frac{4}{5}\)

20) 3 \(\frac{1}{7}\) - 1 \(\frac{5}{7}\) = 2 \(\frac{8}{7}\) - 1 \(\frac{5}{7}\) = 1 \(\frac{3}{7}\)

21) 2 \(\frac{8}{15}\) - 1 \(\frac{9}{15}\) = 1 \(\frac{23}{15}\) - 1 \(\frac{9}{15}\) = \(\frac{14}{15}\)

22) 1 - \(\frac{3}{4}\) = \(\frac{4}{4}\) - \(\frac{3}{4}\) = \(\frac{1}{4}\)

23) 7 - 1 \(\frac{7}{8}\) = 6 \(\frac{8}{8}\) - \(\frac{7}{8}\) = 5 \(\frac{1}{8}\)

24) 3 \(\frac{3}{9}\) - \(\frac{4}{15}\) = \(\frac{30}{9}\) - \(\frac{4}{15}\) = \(\frac{10}{3}\) - \(\frac{4}{15}\) = \(\frac{50}{15}\) - \(\frac{4}{15}\) = \(\frac{46}{15}\) = 3 \(\frac{1}{15}\)

25) 10 \(\frac{1}{2}\) - 4 \(\frac{9}{14}\) = 10 \(\frac{7}{14}\) - 4 \(\frac{9}{14}\) = 9 \(\frac{21}{14}\) - 4 \(\frac{9}{14}\) = 5 \(\frac{12}{14}\) = 5 \(\frac{6}{7}\)

26) 3 \(\frac{5}{9}\) - 1 \(\frac{5}{6}\) = 3 \(\frac{10}{18}\) - 1 \(\frac{15}{18}\) = 2 \(\frac{28}{18}\) - 1 \(\frac{15}{18}\) = 1 \(\frac{13}{18}\)

27) 2 \(\frac{8}{15}\) - 1 \(\frac{13}{15}\) = 1 \(\frac{23}{15}\) - 1 \(\frac{13}{15}\) = \(\frac{10}{15}\) = \(\frac{2}{3}\)

28) 3 \(\frac{1}{7}\) - 1 \(\frac{5}{7}\) = 2 \(\frac{8}{7}\) - 1 \(\frac{5}{7}\) = 1 \(\frac{3}{7}\)

29) 11 \(\frac{3}{5}\) - 5 \(\frac{4}{5}\) = 10 \(\frac{8}{5}\) - 5 \(\frac{4}{5}\) = 5 \(\frac{4}{5}\)
