When elements combine,they do so in a ratio of small whole numbers.
The law of multiple proportions was proposed by John Dalton in 1804; today this law has not a general validity.
Well definite is broad and multiple is more exact that's about what I can think of
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. Two examples of the law of multiple proportions are carbon monoxide, CO, and carbon dioxide, CO2, and water, H2O, and hydrogen peroxide, H2O2.
The law of multiple proportions can be partly explained by the idea that whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.

John Dalton
The law of multiple proportions was proposed by John Dalton in the early 19th century. It states that when elements combine to form compounds, the ratio of masses of one element that combines with a fixed mass of the other element can be expressed in small whole numbers.
No, modern studies have not shown the law of multiple proportions to be invalid. This fundamental principle in chemistry, proposed by John Dalton, states that when elements combine to form compounds, the ratio of masses of one element that combine with a fixed mass of the other element is a simple whole number ratio. This law has been supported by numerous experiments and observations over the years.
Water and hydrogen peroxide
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
