What does .1% mean?

Question

I am reading a paper on a certain issue , that said it
had an incidence of .1 %. I am horrible , horrible at math.
How many people would this be?

Im assuming it is world population.

I would appreciate anyone who could show me.

Answer 1

Well, it depends on the number of people alive at the time of the incident you are reading about. It means that it didn't effect 99.9% of the rest of the population.

Answer 2

One Tenth of One Percent or in decimals .001

So if it is the world population or the population of any kind take the number and multiply it by .001 and you would get the results.

Example .1% of 5,000 people have broken fingers. How many people is that?

5,000 people X .001 = 5 people.

Now the easy way to compute that is that .1% is 1 out of 1000.
So take the number and drop the first three 0's and you have your answer.

Answer 3

In maths,
All % signs are in this format:
(Some number)% of (Another number)
Whenever you see a percent sign straight away put divided by 100 next to it.
If we take an example,
Let there be 1% of 100.
Thus, 1/100 * 100
This is equal to 1. (I hope you know fractions)
So 1% of 100 people is 1 person.

Now in case of decimals,
to change a decimal in fractions,
we count the number of digits after the decimal and divide it by 1 followed by the same number of zeros.
Like in your case, 0.1 = 1 / 10 (Since there is only 1 digit after decimal, we add only 1 zero after 1 in the denominator)

Now you asked what was 0.1%
In this we add 3 zeros after 1 in the denominator (we add two because there is a % sign and one because there is 1 number after decimal)
Thus it becomes: 1/ 1000
Suppose there are 1000 people
So 0.1% of 1000 people would be 1


I hope I didn't make it too complicated to understand!

Answer 4

This is read "one tenth of one percent". Since 1 percent
is 1/100 then .1% is 1/1000(1 thousandth).
Read answer from mikeae for the arithmetic.

Answer 5

given that changing percent to decimal is dividing it by 100 or moving te decimal point 2 places to the left
.1%--->.001 or 1 for every 1000 people

assuming we're at 2.2 billion int the worldthat would be: 2.2 million or 2,200,000 people

Answer 6

1 out of 100.

Answer 7

.1 %

.1/100 = 0.001

.1 divided by 100 equals a decimal equivalent of 0.001

Answer 8

if it is .1% then 1 out of every 1000 and if it is 1% then 1 out of every 100

i think this would be 1 in a 1000

Answer 10

THAT MEANS 1 IN 1000.
