and i think its in whole numbers, not decimal numbers.

Hydrogen has a molecular weight of one. Oxygen has the molecular weight of sixteen.
There are 2 hydrogen atoms in water, and just 1 of oxygen.
Therefore, water weighs 2x1, plus 1x 16. Water weighs 18. The hydrogen is still 2x1, which equal 2.
Divide 18/2, and the answer is 9.
I think that we're misspelling hydrogen.

the ratio of weight of equal volume of water and hydrogen at similar conditions of temperature and pressure is the ratio of formula weight or molecular weight of water and hydrogen,
mol. wt. of H2O=18
mol. wt. of H2=2
ratio=18:2=9

hydrogen gas has a density of 2.016 g/22.4L, at STP. Under the same conditions, water has a density of 1g/mL.
The weight ratio of H2 to H20 is 0.0000892. Inverting this you get H2O/H2 = 11,133.2
