Выполни действие: 5+3/8= 4 8/9+3= 2/5+1 1/5 5 6/11-4/11= 7 3/4-5= 3 2/7-2/7= 2 5/14+1 3/14= 5 11/19-3 6/19= 1-3/10=

Выполним действия, если необходимо выполним некоторые преобразования дроби:

1) 5 + 3/8 = 5 3/8;

2) 4 8/9 + 3 = 7 8/9;

3) 2/5 + 1 1/5 = 1 + 1/5 + 2/5 = 1 + (1 + 2)/5 = 1 + 3/5 = 1 3/5;

4) 5 6/11 - 4/11 = 5 + 6/11 - 4/11 = 5 + (6 - 4)/11 = 5 + 2/11 = 5 2/11;

5) 7 3/4 - 5 = 7 - 5 + 3/4 = 2 + 3/4 = 2 3/4;

6) 3 2/7 - 2/7 = 3 + 2/7 - 2/7 = 3;

7) 2 5/14 + 1 3/14 = 2 + 1 + 5/14 + 3/14 = 3 + (5 + 3)/14 = 3 + 8/14 = 3 8/14;

8) 5 11/19 - 3 6/19 = 5 - 3 + 11/19 - 6/19 = 2 + (11 - 6)/19 = 2 + 5/19 = 2 5/19;

9) 1 - 3/10 = 10/10 - 3/10 = (10 - 3)/10 = 7/10.
