Пошаговое объяснение:
1 1/2 х 2 10/13 + 2 3/4 х 2 10/13 - 2 10/13 х 3 1/6 =
= 2 10/13 * (1 1/2 + 2 3/4 - 3 1/6) = 36/13 * 13/12 = 36/12 = 3
2. 10/13 * (1. 1/2 + 2. 3/4 -
3. 1/6) =
2. 10/13 * (1. 6/12 + 2. 9/12 -
3. 2/12) =
2. 10/13 * (3. 15/12 - 3. 2/12) =
2. 10/13 * 13/12 = 36/13 * 13/12 = 36/12 = 3
