Answer 1

convert everything to the same units

first you have to know what they all mean so:

mm=millimeter

cm=centimeter

m=meter

km=kilometer

same holds true for grams and liters

mg

cg

g

kg   and so on

now milli means 1/1000

so a millimeter means 1/1000th of a meter

centi means 1/100

kilo means 1000  so kilogram means 1000 grams

doing your problems :

795 cg= 795 * 1/100 g = 795/100 g = 7.95 g

42205 cm = 42205 * 1/100 m = 42205/100 m = 422.05 m

4566 km = 1000m * 4566 = 4566000 m
