PLEASE HELP ME...I WILL GIVE YOU BRAINLIEST. MMMEE #1. Use milligrams to prove that 1.989 . 10^27 kilograms is equal to 1.989 · 10^33 milligrams.
#2. Use kilograms to prove that 1.989 - 10^33 milligrams is equal to 1.989 . 10^27 kilograms.

Since 1 milligram is or kilogram we can then use ratio to solve.

Step-by-step explanation:

#1)

1  :  

x :  1.989*10^27

Cross multiply to get:

x = 1.989*10^27

Divide both sides by to get:

x = 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  :  

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
