Can you replace each alphabet with the number (1 - 9) to make below equation correct ?

AB * C = DE - F = GH / I

39 * 1 = 45 - 6 = 78 / 2

AB - C = DE / F = GH * I can be solved as

A = 3

B = 9

C = 1

D = 4

E = 5

F = 6

G = 7

H = 8

I = 2

So below equation can be solved as:

AB - C = DE / F = GH * I

39 * 1 = 45 - 6 = 78/2

39 = 39 = 39.
