a) [0,8 - (1,2 * 5/12 - 0,8)]:(- 1/8) = [0,8 - 12/10 * 5/12 + 0,8]*(- 8) = [1,6 - 0,5]*(- 8) = - 8,8

a) [(- 1/2):(- 2) - 5/36]/[(- 1):(- 9)] + 4:(- 2,5) = [1/4 - 5/36]/[1/9] + 4:(- 5/2) = [9/36 - 5/36]/[1/9] - 8/5 = [4/36]/[1/9] - 8/5 = 1 - 8/5 = - 3/5 = - 0,6
b) [(- 5/6) : 2,5 - (- 2,25) * 1/9]/[0,2 - (- (- 1))] = [(- 5/6) : 5/2 + 9/4 * 1/9]/[0,2 - 1] = [- 2/6 + 1/4]/[- 8/10] = [- 4/12 + 3/12]/[- 8/10] = [- 1/12]/[- 8/10] = 10/12*8 = 5/48
