Выполните действия: 1) 1/2 + 2/3; 2) 1/5 + 1/2; 29) 8/9 − 2/9 + 5/18; 30) 8/9 − 4/30 + 11/15; 13) 7 3/8 + 1 7/10; 14) 2 1/8 + 3 5/12.

1. \(\frac12+\frac23=\frac3{6}+\frac4{6}=\frac76=1\frac16\).
2. \(\frac15+\frac12=\frac2{10}+\frac5{10}=\frac7{10}\).
3. \(\frac89-\frac29+\frac5{18}=\frac69+\frac5{18}=\frac{12}{18}+\frac5{18}=\frac{17}{18}\).
4. \(\frac89-\frac4{30}+\frac{11}{15}=\frac{40}{45}-\frac6{45}+\frac{33}{45}=\frac{67}{45}=1\frac{22}{45}\).
5. \(7\frac38+1\frac7{10}=8+\frac{15}{40}+\frac{28}{40}=8\frac{43}{40}=9\frac3{40}\).
6. \(2\frac18+3\frac5{12}=5+\frac3{24}+\frac{10}{24}=5\frac{13}{24}\).

Ответ: 1) \(1\frac16\); 2) \(\frac7{10}\); 29) \(\frac{17}{18}\); 30) \(1\frac{22}{45}\); 13) \(9\frac3{40}\); 14) \(5\frac{13}{24}\).
