помогите пожалуйста!!! дам 20 балов быстреее​

Answer 1

Ответ:

1. $2\frac{1}{24}$

2. $0,3527$

3. $\frac{1}{3}$

4. $1\frac{3}{5}$

5. $1\frac{1}{18}$

6. 1,36

Пошаговое объяснение:

1. $\frac{5}{8} +\frac{5}{6} +\frac{7}{12} =\frac{15+20+14}{24} =\frac{49}{24} =2\frac{1}{24}$

2. $\frac{1}{5} +\frac{3}{8} -\frac{2}{9} =\frac{72+135-80}{360} =\frac{127}{360} =0,3527$

3. $\frac{1}{4} +\frac{2}{9} -\frac{x5}{36} =\frac{9+8-5}{36} =\frac{12}{36} =\frac{1}{3}$

4. $\frac{3}{4} +\frac{4}{5} +\frac{1}{20} =\frac{15+16+1}{20} =\frac{32}{20} =\frac{8}{5} =1\frac{3}{5}$

5. $\frac{3}{4} +\frac{5}{12} -\frac{1}{9} =\frac{27+15-4}{36} =\frac{38}{36} =\frac{19}{18} =1\frac{1}{18}$

6. $\frac{4}{15} +\frac{2}{5} +\frac{7}{10} =\frac{8+12+21}{30} =\frac{41}{30} =1\frac{11}{30} =1,36$
