Answer 2

Пошаговое объяснение:

1) 40 : (-2 2/15) = 40 : (-32/15) = 40 * (-15/32) = 5 * (-15/4) = 75/4 = -18 3/4

2) 25 5/7 : (-1 1/35) = 180/7 : (-36/35) = 180/7 * (-35/36) = 5/1 * (-5/1) = -25/1 = -25

3) -18 3/4 - (-25) = -18 3/4 + 25 = -18 3/4 + 24 4/4 = 6 1/4

4) -21 7/9 : 4 2/3 = -196/9 : 14/3 = -196/9 * 3/14 = -14/3 * 1/1 = -14/3 = -4 2/3

5) -4 2/3 + 1 = -3 2/3

6) 6 1/4 : (-3 2/3) = 25/4 : (-11/3) = 25/4 * (-3/11) = -75/44

7) -75/44 * (-3 2/3) = -75/44 * (-3 2/3) = -75/44 * (-11/3) = -25/4 * (-1/1) = 25/4 = 6 1/4
