18a² b² c² : -2a³ b³ c

18a² b² c² : -2a³ b³ c

= (18: -2) a^(2-3) b^(2-3) c^(2-1)

=-9 a^(-1) b^(-1) c^1

=( -9c) / (ab)

Answer:
________

18a^2b^2c^2 / -2a^3b^3 c

- 18a^2b^2c^2 / 2a^3b^3 c

-18/2 x a^2b^2c^2 / a^3b^3 c

-9 x a^2b^2c^2 / a^3b^3 c

-9a^2-3 b^2-3 c^2-1

-9a^-1 b^-1 c^1

-9 x 1/a b^-1 c^1

-9 x 1/a x 1/b c^1

-9 x 1/a x 1/b c

-9 x 1 x 1 x c / a x b

9c
- ______
ab
