Helium gas accounts for less than 0.01% of earth's atmosphere gases. write this percentage as a decimal and as a mixed number or fraction in simplest form . then interpret it's meaning

0.01% in decimal form=0.0001 and in fraction form=1/10000

Step-by-step explanation:

Step 1 To convert the percentage in decimal form.

A percentage is a ratio expressed as a fraction of 100.

So, 0.01% means 0.01 out of 100.

Therefore,

0.01%= 0.01/100

0.01%= 0.0001

Step 2: Convert the decimal in fraction form.

Remove the point by dividing by 10000

0.01%= 1/10000

The meaning of the result is that helium account for less than one part per 10000 parts of Earth’s atmosphere gases.
