Сложите дроби: 1) 1/2 + 3/4; 2) 5/6 + 3/8; 3) 3/22 + 1/2; 4) 5/16 + 7/8; 5) 7/10 + 3/25; 6) 3/16 + 5/12; 7) 3/4 + 11/12; 8) 2/9 + 5/6.

Приводим дроби к общему знаменателю и складываем числители.

1. 1/2 + 3/4 = 2/4 + 3/4 = 1 1/4.
2. 5/6 + 3/8 = 20/24 + 9/24 = 1 5/24.
3. 3/22 + 1/2 = 3/22 + 11/22 = 7/11.
4. 5/16 + 7/8 = 5/16 + 14/16 = 19/16 = 1 3/16.
5. 7/10 + 3/25 = 35/50 + 6/50 = 41/50.
6. 3/16 + 5/12 = 9/48 + 20/48 = 29/48.
7. 3/4 + 11/12 = 9/12 + 11/12 = 1 2/3.
8. 2/9 + 5/6 = 4/18 + 15/18 = 1 1/18.
