Question

плиз помогите пожалуйста ​

Answer 1

Пошаговое объяснение:

1) 5 - 11 2/13 = -6 2/13

2) 2 1/13 * (-6 2/13) = 27/13 * (-80/13) = -2160/169 = -12 132/169

3) 2 1/13 - 5 = 2 1/13 - 4 13/13 = -2 12/13

4) 11 2/13 * (-2 12/13) = 145/13 * (-38/13) = -5510/169 = -32 102/169

5) -12 132/169 + (-32 102/169) = -12 132/169 - 32 102/169 = -44 234/169 = -45 65/169 = -45 5/13
