First off, the "compounds in a carbohydrate" are elemental atoms ( not some whipped-up, pre-carbohydrate material. Secondly, there is an immense variety of carbohydrates which can be created by adding carbon, oxygen and hydrogen atoms to more simple carbohydrate molecules.
The ratio depends on the compound.
The chemical elements found in carbohydrates are carbon, hydrogen, and oxygen. The ratio of hydrogen to oxygen in carbohydrates is 2:1, which is the same as the ratio you provided (12:1). This ratio reflects the basic molecular structure of carbohydrates, such as glucose.
Carbohydrates consist of carbon, hydrogen, and oxygen, usually in a ratio of 1:2:1 as: (C1H2O1)n

Both carbohydrates and water contain the elements carbon, hydrogen, and oxygen. Carbohydrates have a specific ratio of these elements, while water is a simple compound with two hydrogen atoms and one oxygen atom.
Carbohydrates are generally made of monosaccharides (i.e. simple sugars), like glucose (C6H12O6). As a result, the ratio of elements for carbohydrate sugars (C:H:O) would be 1:2:1.
Carbohydrates are composed of Carbon, Hydrogen , and Oxygen. Usually in ratio close to 1:2:1.
Carbon, hydrogen, and oxygen are the chemical elements in carbohydrates.
The ratio of carbohydrates to all other matter in the universe is very, very close to 0.
