A = 17/3-10 = 17/ -7

B = - 2-(-17)/5-8 = - 2 + 18 /-3 = 16/-3

C = - 4 - 5 / 5 - 6 = - 9 /-1 = 9

D = 6 - 6 x 4 / 6 x 2 - 2 = 6 - 24 / 12 - 2 = - 18 / 10 = -1,8

E = 2 - -18 /-3 + 6 = 2 - 6 + 6 = 2

F = (-21) + 7 x 3 / (-13) + 17 x (-4) = (-21)+21 / (-13)-68 = 0 / 81 = 0

G = -2x(-4)x3x(-3) / (-4,5)x2 = 8x(-9) / - 9 =-72/-9 = 8

H = -5x(-3)x(-4) / (-1)x(-1)x(-1) = 15x(-4)/-1 = - 60 / -1 = 60

I = -9x(-3)-(-3)x(-5) / 15+(-3)-2 = 27 - 15 / 12 - 2 = 12 / 10 = 1,2

16/-3 < 17/-7 < -1,8 < 0 < 1,2 < 2 < 8 < 9 < 60

B < A < D < F < I < E < G < C < H
