Since 1 milligram is $\frac{1}{10^{6} }$ or $10^{-6}$ kilogram we can then use ratio to solve.

Step-by-step explanation:

#1)

1 : $10^{-6}$

x : 1.989*10^27

Cross multiply to get:

$10^{-6}$ x = 1.989*10^27

Divide both sides by $10^{-6}$ to get:

x = $\frac{ 1.989*10^{27}}{10^{-6}}$ which is going to give you 1.989*10^33

Therefore 1.989*10^27 kilograms = 1.989*10^33 milligrams

#2) we can use the same procedure as (#1)

1 : $10^{-6}$

1.989*10^33 : x

Cross multiply to get:

1.989*10^27 = x

Therefore 1.989*10^27 milligrams = 1.989*10^33 kilograms

Note: I'm not really sure if this is what you wanted, but hope I was able to help.
