Question

Выполни действие 8/15-3/15+10/15 24/31-11/31-5/31+7/31= (18/29+13/29)-(25/29-11/29)= (29+46+31/46)-(19/46+21/46)=

Answer 1

1. 1
2. 15/31
3.17/29
4. 20/46

Answer 2

Давайте посчитаем каждое действие по шагам:

1. 8/15 - 3/15 + 10/15 = (8 - 3 + 10) / 15 = 15/15 = 1

2. 24/31 - 11/31 - 5/31 + 7/31 = (24 - 11 - 5 + 7) / 31 = 15/31

3. (18/29 + 13/29) - (25/29 - 11/29) = (18 + 13) / 29 - (25 - 11) / 29 = 31/29 - 14/29 = 17/29

4. (29 + 46 + 31)/46 - (19/46 + 21/46) = (106/46) - (40/46) = 66/46 = 33/23

Итак, результаты вычислений:

1. 8/15 - 3/15 + 10/15 = 1
2. 24/31 - 11/31 - 5/31 + 7/31 = 15/31
3. (18/29 + 13/29) - (25/29 - 11/29) = 17/29
4. (29 + 46 + 31)/46 - (19/46 + 21/46) = 33/23
