How many grams are in two dekagrams?
If one gram of water has a volume of one milliliter, what would the mass of one liter of water be in kilograms?
what part of a meter is a decimeter?
(I dont understand this...how do you get those answers?)

To convert units in the metric system, try to remember that
1) it is a decimal system--i.e. they're all multiples of ten of each other.
2) Remember the following sentence:
King Henry Died Mary/Guen/Liz Didn't Care Much.
King = Kilo = 1,000 = 10^3
Henry = Hecto = 100 = 10^2
Died = Deca = 10 = 10^1
Mary = meter/Guen = gram/Liz = liter
Didn't = Deci = .1 or 1/10 = 10^-1
Care = Centi = .01 or 1/100 = 10^-2
Much = milli = .001 or 1/1000 = 10^-3
Just use the first letters:
K H D M/G/L d c m
The meter is used for linear or straight line distance, the gram is used for mass and the liter is a unit of volume.
So, for your question:
1g of water = volume of 1 milliliter or .001 liters.
A "milli" is 1/1000 of a whole. This means there are 1,000 milliliters in a Liter. If 1 gram of water has the volume of 1/1000 liters, then a thousand grams or 1 Kilogram of water must have the volume of 1,000 milliliters or 1 liter. So, 1 liter of water has a mass of 1 kilogram.
For the meter and decimeter part, use the sentence.
K H D M[eter] d c m.
To go from decimeter to meter, you move over from the d [Didn't] to the M [Mary]. or, one decimal place to the left. So, 1 decimeter is, moving over one place left, 0.1 meters--or 1/10 of a meter. This works both directions. In other words, to go from 1 kilomter to how many centimeters, one would move the decimal place to the right 5 places: 1 kilometer = 100,000 centimeters.

1 meter = 10 decimeters,
1 meter = 100 centimeters,
1 meter = 1000 millimeters;
1 kilogram = 1000 grams
Answers: If 1 gram of water = 1 milliliter, 1 milliliter = 1 gram, so 1 liter water = 1 kilogram (mass)
2 decagrams = 0.2 grams (?)

No.1.... one milliliter equals 1/1000 of liter
so, it is one part of the one thousand parts of a liter
and it equals one gram in mass
so, the one thousand parts (liter) will equal
1 gram x1000 parts=1000 grams which equal 1 Kilogram
No.2. Every meter has 100 Cms
Every decimeter equals 10 Cms
So, every one meter equals 10 decimeters

To get you started 1 deca = 10
so two deca = 2 X 10 or 20
therefore20 grams in 2 decagrams
see the source below for more prefixes

i always draw these steps out
King (Kilo)
Henry (Hecto)
Doesn't (Deka)
Milk (Meter, Liter, Gram)
Dairy (Deci)
Cows(Centi)
Monday(Milli)
You start in the middle (Milk)
lets sat you have 5.67 Meters and you have to convert to Millimeters
You take 3 steps down, so carry the decimal point to the right 3 spaces 5.67 meters=5670 millimeters

1 litre of water is always assumed to be 1kg. That's what we use in mechanical engineering and science. Its just a given.
A decimetre is the same as 1m x 1/1000
