Задание 264

1) $\frac{5}{6} - \frac{3}{8} = \frac{20-9}{24} = \frac{11}{24}$

2) $\frac{3}{10} -\frac{2}{25} = \frac{15-4}{50} =\frac{11}{50}$

3) $\frac{2}{9} - \frac{9}{15} = \frac{10-6}{45} = \frac{4}{45}$

4) $\frac{7}{20} - \frac{7}{30} = \frac{21-14}{60} = \frac{7}{60}$

Задание 266

1) $\frac{29}{30} - \frac{23}{30} = \frac{29-23}{30} = \frac{6}{30} = \frac{1}{5}$

2) $\frac{29}{30} -\frac{1}{15} = \frac{29-2}{30} = \frac{27}{30} = \frac{9}{10}$

3) $\frac{29}{30} - \frac{1}{4} = \frac{58-15}{60} = \frac{43}{60}$

4) $\frac{29}{30} -\frac{1}{3} = \frac{29-10}{30}= \frac{19}{30}$

Задание 270

1) $\frac{11}{12} + \frac{3}{4} - \frac{7}{18}= \frac{33+27-14}{36} = \frac{46}{36} = \frac{23}{18} =1\frac{5}{18}$

2) $\frac{29}{30} - \frac{2}{15} + \frac{1}{3} = \frac{29-4+10}{30} = \frac{35}{30} = \frac{7}{6} = 1\frac{1}{6}$

3) $\frac{6}{7} - \frac{3}{14} + \frac{11}{35} = \frac{60-15+22}{70}= \frac{67}{70}$

Задание 272

1) $\frac{23}{24} - \frac{2}{3} = \frac{23-16}{24} = \frac{7}{24}$

2) $\frac{23}{24} - \frac{3}{4} = \frac{23-18}{24} = \frac{5}{24}$

3) $\frac{23}{24} - \frac{7}{12} = \frac{23-14}{24} = \frac{9}{24} = \frac{3}{8}$

4) $\frac{23}{24} - \frac{5}{18} = \frac{69-20}{72} = \frac{49}{72}$
