Step-by-step explanation:

Prime numbers until 15: 2,3,5,7,11,13. That are 6, and so 6/15 or 2/5 of the natural numbers from 1 to 15 are prime.

Answer 2

As per the data given in the question,

We have to determine that what percentage of natural number between 3 and 15 are prime numbers.

So, let us first understand that what exactly is natural number and prime numbers.

As we know that,

natural numbers are counting numbers.

So, natural number between 3 and 15 will be 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,14, 15

Total numbers = 13

As we know that,

Prime numbers are those numbers which have only two factors or we can say that such numbers which or either divisible by 1 or itself are called as Prime numbers.

So, prime number among 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14 will be 3, 5, 7, 11, 13.

So, total prime numbers between 3 and 15 will be 5

So, now determining the fraction value,

So, the required fraction value will be $\frac{5}{13}$.

Hence.  $\frac{5}{13}$ of numbers between 3 to 15 are prime numbers.
