Answer 2

Step-by-step explanation:  

To find: Natural numbers from $2\ to\ 15$  

The fraction of prime numbers between $2\ to\ 15$.  

• We know Natural Numbers are the simple positive counting numbers.  So, the natural numbers from $2\ to\ 15$     are;

      ⇒  $2,3,4,5,6,7,8,9,10,11,12,13,14\ and \ 15$  

• Also, Prime numbers are those numbers which are only divisible by themselves and 1. For example, $3,7,11 \ etc.$  So, the prime numbers from $2\ to\ 15$     are;

      ⇒ $2,3,5,7,11,13$

• Hence,

     ⇒ No. of prime numbers$=6$  

     ⇒ Total numbers $=14$  

     ⇒ Fraction $=\frac{6}{14}$  

     ⇒ Reduced form $= \frac{3}{7}$
