0.4 per 1000 of the general population.
What percent is that?
And how many people would that equal out to?
How many people is that per 1,000,000?
sorry im horrible at math.

10% is 100 per 1000
1% is 10 per 1000
.1% is 1 per 1000
.04%is 0.4 per 1000
That is equal to less than 1 person per 1000 people
.04% of 1 million is .04 x 1,000,000 or 400 people

0.4 per 1000 is a ratio. If you'd like to write it as a percent, divide 0.4 by 1000, then move the decimal point two places to the right.
0.4 ÷ 1000 = 0.0004 = 0.04%
For 0.4 per 1000 to be equal to n per 1,000,000, there are a number of ways to find n. First, since you now know the percent, multiply 0.04% by one million:
0.04% Ã 1,000,000 = 0.0004 Ã 1,000,000 = 400 people.
Another way to do it is to set up a proportion and cross-multiply to solve:
0.4 / 1000 = n / 1,000,000
0.4 Ã 1,000,000 = 1000 Ã n
400,000 = 1000n [Divide both sides by 1000.]
400 = n. n, again, is 400 people.
Oh, and don't apologize for being "horrible" at math. The fact that you're asking a question means you're trying to learn. :-)

The percentage is 0.04%
How? 0.4/1000 X 100% = 0.04%
How many people isit equal to depends on the number of people in the population. Denote all the people in the population as "S"
thus, its 0.04% or 0.04/100 x S
Say the "S" is 1,000, 000 like u asked:
thus 0.04/100 x 1,000,000 = 400 people.
hope u get it now.

0.4 per 1,000 is the same as 0.04%
That would equal out to 4 people per 10,000... and 400 people per 1,000,000

0.4/1000 is a fraction. to convert a fraction to percentage multiply by hundred that is 0.04
per 1,000,000=1,000,000*0.04/100
=400
