помогите сложить дроби: 2/10+6/15
3/4+5/18
2/9+5/6
5/12+4/15

[tex]\frac{2}{10}+\frac{6}{15}=\frac{6}{30}+\frac{12}{30}=\frac{18}{30}=\frac{3}{5}=0,6[/tex]
[tex]\frac{3}{4}+\frac{5}{18}=\frac{27}{36}+\frac{10}{36}=\frac{37}{36}=1\frac{1}{36}[/tex]
[tex]\frac{2}{9}+\frac{5}{6}=\frac{4}{18}+\frac{15}{18}=\frac{19}{18}=1\frac{1}{18}[/tex]
[tex]\frac{5}{12}+\frac{4}{15}=\frac{25}{60}+\frac{16}{60}=\frac{41}{60}[/tex]
