well, the last part will be with a calculator, but you can simply use the area in π terms.
Answer: 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.
Answer:
Mixed number: 
Improper fraction: 
Step-by-step explanation:
A mixed number is a number that contains an integer part and a fraction part.
An improper fraction is a fraction where the numerator is greater than the denominator.
can be written as in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.
The mixed number is since 
goes into 
three full times and the remainder is 
.
∴The mixed number is and the improper fraction is .
