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:(

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.
Jupiter's atmosphere is primarily composed of hydrogen (around 75%) and helium (around 24%), with trace amounts of other gases such as methane, ammonia, and water vapor. The exact percentages can vary slightly depending on the specific region of the atmosphere being measured.
Greenhouse gases in the atmosphere are measured using instruments like spectrometers and satellites that can detect and quantify the concentration of these gases in the air. Scientists collect data from various locations around the world to monitor and track changes in greenhouse gas levels over time.
Nitrogen (about 78%) and oxygen (about 21%).

Diversity on a college campus is measured by how many of each race there are on campus. From there, percentages are derived based on the findings and that is how it's done.

There is no way to answer this. Percentage of what? Percentages are comparison of two things measured in the same way.
Hydrogen peroxide is a liquid compound and does not have volumes in the same way that gases or solids do. It is typically sold and measured by its concentration in percentages, such as 3% or 6% hydrogen peroxide.
