3/14 is the fraction.

Answer 2

Answer:

Required fraction is $\frac{3}{14}$

Step-by-step explanation:

Natural number is all positive integer which always starts from 1.

For example 1,2,3,4 e.t.c

Now we want to find all natural numbers between 50 and 65.This is very easy.

All natural numbers between 50 and 65 are

$51,52,53,54,55,56,57,58,59 ,\\ 60,61,62,63,64$

Now from these numbers,we need to find all prime numbers.

But question is what are prime numbers ?

Prime numbers are always divisible by only 1 and ownself.For example 3 is a prime number because 3 is always divisible by 1 and 3.

Again 11 is a prime number because divisors of 11 are 1 and 11 only.

Now prime numbers between 50 and 65 are $53,59,61$

Now 50 to 65,there are total 14 numbers and there are 3 prime numbers between 50 and 65.

So,14 means 1 part (in fraction)

By Unitary method,

1 means $\frac{1}{14}$part

and 3 means $\frac{3}{14}$
