Oxygen
30 percent of 20 percent of 150 percent = 0.09
20 percent of 80 percent = 0.16 or 16%
20% = .20 20% of 1m = .20 * 1m = 0.2m
"percent" means "out of 100"20 percent of 5000 is:20/100 x 5000 = 1000Correct - as far as it goes.But the question was not 20 percent of 5000, it was 20 percent of 5000 percent.So the answer is 1000 percent. And that, in turn, gives the correct answer of 10

oxygen
the percentage of oxygen in the atmosphere today is about 20.95%. Or... if you round it you get the most common answer of 21%.
Earth's atmosphere is 20 percent oxygen and 80 percent nitrogen. In space, there is no oxygen due to the lack of gravity to help it form.
21% of the atmosphere is oxygen.
Oxygen is still 20 percent of the earth's atmosphere.
Oxygen (O2)
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
The atmosphere would be much more volatile.
