It is a convention, not absolutely rational.
Carbon, Hydrogen, and Oxygen ine the ratio of 1:2:1
There are 12 carbon atoms in a molecule of maltose. Each carbon atom forms a total of four bonds, which include bonds with other carbon atoms, hydrogen atoms, or oxygen atoms. With 12 oxygen atoms present, these atoms would be accounted for in the molecular structure of maltose as well.
Why not? Some standard was needed; carbon-12 was as good as any. The important thing was that everyone agreed on it. The previous standard had been oxygen; unfortunately, some people had used oxygen-16 specifically and some people had used standard natural abundance oxygen (a mixture of isotopes). Carbon-12 had the advantages of being a) specific, b) fairly common, and c) not oxygen.
The ratio of oxygen to carbon when 32 g of oxygen combine with 12 g of carbon is 8:3. This can be calculated by dividing the mass of each element by their respective atomic masses to find the number of moles, then dividing the moles of oxygen by the moles of carbon to find the ratio.
Glucose is a carbohydrate, which means it contains carbon, hydrogen, and oxygen. Specifically, glucose contains 6 carbon, 6 oxygen, and 12 hydrogen atoms.
The ratio of carbon atoms to oxygen atoms in table sugar (sucrose) is 12:11. This means that for every 12 carbon atoms, there are 11 oxygen atoms in the molecular formula of sucrose (C12H22O11).
12 carbons...
The chemical formula for maltose is C12H22O11, so there are a total of 12 carbon atoms in a molecule of maltose. A molecule of maltose has 11 oxygen atoms, not 12.
Which sugar. There are many different sugars and the ratio can vary. If you mean sucrose, there are 12 carbons and 11 oxygens, so ratio of carbon to oxygen is 12:11

Carbon is taken as a standard. It replaced oxygen in 1961.
