Вычислите (1-3/13+2-2/13)+3-7/13= 5-7/18+(4-11/18+2-10/18)= 5-5/17+(6-16/17+13-8/17)= 11-16/23+(4-14/23+7-13/23)=

Вычислим значение выражения, сложим целые значения с целыми, а дроби с дробями:

1. (1 - 3/13 + 2 - 2/13) + 3 - 7/13 = 3 - 5/13 + 7 - 7/13 = 10 - 12/13 = 9 + 1 - 12/13 = 9 + 13/13 - 12/13 = 9 + 1/13 = 9 1/13.

2. 5 - 7/18 + (4 - 11/18 + 2 - 10/18) = 5 - 7/18 + 6 - 21/18 = 11 - 28/18 = 11 - 1 10/18 = 10 - 5/9 = 9 + 9/9 - 5/9 = 9 4/9.

3. 5 - 5/17 + (6 - 16/17 + 13 - 8/17) = 5 - 5/17 + 19 - 24/17 = 24 - 29/17 = 23 - 1 + 17/17 - 12/17 = 22 5/17.

4. 11 - 16/23 + (4 - 14/23 + 7 - 13/23) = 11 - 16/23 + 11 - 27/23 = 22 - 43/23 = 21 - 1 + 23/23 - 20/23 = 20 3/23.
