# If something is 0.3 percent of the population, how does this work? Because zero has no value. Can someone explain?

0.3% = 0.3/100 = 0.003

Multiply the population by 0.003 to get the number of the "something". If the population is 5000, then 0.3% is 5000*0.003 = 15

You comment "Because zero has no value" is confusing and suggests some misunderstanding somewhere. How does zero enter into the problem/question? If the population is zero, then it follows that 0.3% of zero is also zero.

how does this work?

Because zero has no value.

Can someone explain?

One-tenth of 3 percent is 0.3 percent.

If you're talking about the leading zero before the decimal point, that is only commonly put there to indicate there is no other value before the decimal. 0.3 and .3 are exactly the same value.

If there is a decimal sign then 0 has a significance. ie. 1 in 100 is written as 0.01.

0.3 is still larger than 0 so it has a value, ie 3/10 ths of one percent.

0.3% is 3 parts out of 1000.

3% is 3 parts out of 100

0.03% is 3 parts out of 10000

what does zero have to do with this?
