Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Gases in the atmosphere are measured in percentages to provide a clear and standardized way of expressing their concentration relative to the total volume of air. This percentage format makes it easier to compare the abundance of different gases, such as oxygen, nitrogen, and carbon dioxide, and to understand their roles in processes like respiration and climate change. Additionally, using percentages helps scientists and researchers communicate findings effectively across various disciplines.
Percentages are percentages - simple! The marketing people have not yet come up with "new improved" percentages.

The answer depends on what you are trying to do with the percentages.
i don't know the percentages but i do know that hydrogen and helium are the 2 main gases! sorry this did not completely answer the question:(
oxygen
Showing the amount of gases in the atmosphere as percentages of dry air allows for easy comparison and analysis of the composition of the atmosphere. Since the composition of dry air is relatively stable, expressing the gases as percentages of dry air helps to standardize the data for scientific purposes.
Nitrogen (about 78%) and oxygen (about 21%).
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Most people work with percentages in one way or another.

Ambient air is about 21% Oxygen, 78% Nitrogen and 1% Mixed Gasses. Our body uses about 4% Oxygen to stay alive so what comes out is 17% Oxygen and 4% Carbondioxide.

Credit scores are used to determine loan percentages when a person applies for a loan. If a person has a low credit score, the percentages of interest are higher, whereas higher credit scores result in lower loan percentage rates.
