Answer 1

Я ничего не понял из вашего вопроса, только по фотографии. Решу всё.

459.

1) $\frac{3}{5} и \frac{5}{6} = \frac{18}{30} и \frac{25}{30}$

2) $\frac{6}{11}и\frac{4}{9} = \frac{54}{99} и \frac{44}{99}$

3) $\frac{5}{6} и \frac{4}{11} = \frac{55}{66} и \frac{24}{66}$

4) $\frac{7}{18} и \frac{1}{6} = \frac{7}{18}и\frac{3}{18}$

5) $\frac{9}{13} и \frac{4}{5} = \frac{45}{65},\frac{52}{65}$

6) $\frac{5}{7},\frac{3}{4} = \frac{20}{28} и \frac{21}{28}$

7) $\frac{2}{15} и \frac{1}{3} = \frac{2}{15}и\frac{5}{15}$

8) $\frac{5}{8}и\frac{3}{4} = \frac{5}{8}и\frac{6}{8}$

460.

1) $\frac{1}{2},\frac{1}{6};\frac{2}{3} = \frac{3}{6},\frac{1}{6};\frac{4}{6}$

2) $\frac{1}{4},\frac{5}{7};\frac{9}{28} = \frac{7}{28},\frac{20}{28};\frac{9}{28}$

3) $\frac{1}{5},\frac{11}{20};\frac{3}{10} = \frac{4}{20},\frac{11}{20};\frac{6}{20}$

4) $\frac{3}{4},\frac{7}{8};\frac{3}{16} = \frac{12}{16},\frac{14}{16};\frac{3}{16}$

5) $\frac{2}{3},\frac{2}{15};\frac{4}{5} = \frac{10}{15},\frac{2}{15};\frac{12}{15}$

6) $\frac{1}{2},\frac{1}{9};\frac{5}{6} = \frac{9}{18},\frac{2}{18};\frac{15}{18}$

461.

1) $\frac{7}{20},\frac{5}{12} = \frac{21}{60},\frac{25}{60}$

2) $\frac{11}{24},\frac{1}{30} = \frac{55}{120},\frac{4}{120}$

3) $\frac{3}{16},\frac{7}{12} = \frac{9}{48},\frac{28}{48}$

4) $\frac{11}{18},\frac{7}{12} = \frac{22}{36},\frac{21}{36}$

5) $\frac{1}{12},\frac{2}{9} = \frac{3}{36},\frac{8}{36}$

6) $\frac{4}{21},\frac{13}{28} = \frac{16}{84},\frac{39}{84}$

7) $\frac{8}{15},\frac{5}{12} = \frac{32}{60},\frac{25}{60}$

8) $\frac{7}{30},\frac{1}{12} = \frac{14}{60},\frac{5}{60}$
