Answer 1

(-2,5-1 5/6):1 4/9-3 5/9*-2 1/4

(-2,5 - 1 5/6) : 1 4/9 - 3 5/9 * (-2 1/4) = 5

1) - 2,5 - 1 5/6 = - (25/10 + 11/6) = - (75/30 + 55/30) = - 130/30 = - 13/3

2) - 13/3 : 1 4/9 = - 13/3 : 13/9 = - 13/3 * 9/13 = - 9/3 = - 3

3) 3 5/9 * (-2 1/4) = 32/9 * (-9/4) = - 32/4 = - 8

4) - 3 - (-8) = - 3 + 8 = 8 - 3 = 5
