One.
Yes, that is true.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
All the positive real numbers are natural numbers.
All of the natural numbers.
There will be one 0 for every time 5 is a factor in the set of natural numbers from 1 to 100. This is 20 when 5 is a factor plus 4 more for when 25 is a factor That is, 24 in all.
Yes, that is true.
Every number has 1 as a factor.
All numbers are not natural numbers.Natural numbers are 1,2,3,4,5....
One is a factor of all nonzero numbers.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
All numbers with 12 as a factor have 2 as a factor, but not all have 10 as a factor.
All the positive real numbers are natural numbers.
The set of rational numbers includes the set of natural numbers but they are not the same. All natural numbers are rational, not all rational numbers are natural.
A prime number is a natural number that has no natural number as a factor other than itself or 1. An irrational number is not a natural number, so an irrational number can't be prime.
Yes. All even numbers have 2 as a factor.
All natural numbers are integers, not all integers are natural numbers.
2 is a divisor of all even numbers, and a divisor is a factor of all numbers which can be divided by it.
