It is 1:2:1
The chemical elements present in monosaccharides are carbon (C), hydrogen (H), and oxygen (O). These elements combine in specific ratios to form different types of monosaccharides, such as glucose, fructose, and galactose.
Monosaccharides are defined by having a carbon, hydrogen, and oxygen ratio of 1:2:1. This means that for every carbon atom, there are twice as many hydrogen atoms and one oxygen atom present in the molecule. This ratio is a characteristic feature of simple sugars like glucose and fructose.

They all contain C, O, H&The ratio H to C is fixed at 2:1
It is 1:2:1
In the universe, the ratio, by mass, is C : H : O = 1 : 150 : 2.
Aspirin has the chemical formula C9H8O4. The Lewis structure of aspirin would involve drawing the skeletal structure of 9 carbon atoms, 8 hydrogen atoms, and 4 oxygen atoms connected by single and double bonds to satisfy the octet rule for each atom in the molecule. The central part of the structure consists of a benzene ring attached to a carboxyl group (–COOH).
The Lewis structure of H3COCH3 (also called dimethyl ether) consists of one oxygen atom double bonded to a carbon atom, with two methyl groups (CH3) each attached to the carbon atoms. All atoms in the molecule satisfy the octet rule and there are no formal charges present.
The elements are C, H and O, at a ratio of 6:8:7.
C : H : O = 1 : 2 : 1 thus CH2O is the simplest ratio formula
The Lewis structure for methanol (CH3OH) consists of a carbon atom bonded to three hydrogen atoms and one oxygen atom. The carbon atom is in the center with single bonds to the three hydrogen atoms and one bond to the oxygen atom. The oxygen atom has two lone pairs of electrons.
The Lewis structure of H2CO3 (carbonic acid) has two oxygen atoms double bonded to the carbon atom, and one hydroxyl group (OH) single bonded to the carbon atom. Each oxygen atom has two lone pairs of electrons around it, while the carbon atom has two lone pairs as well.
