Answer 1

Natural numbers from 2 to 10 are 2, 3, 4, 5, 6, 7, 8, 9, 10, . Prime numbers among these are 2, 3, 5, 7, Therefore, out of 2, 5 are prime numbers. It represents a fraction (2,5)

Answer 2

Answer:

There are 9 natural numbers from 2 to 10 and fraction of prime number is $\frac{4}{9}$

Step-by-step explanation:

To Find: How many natural numbers are there from 2 to 10? What fraction of them are prime numbers?

Solution:

Natural numbers: The positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.

No. of natural numbers from 2 to 10 = {2,3,4,5,6,7,8,9,10}=9

Prime numbers : A number that is divisible only by itself and 1 is prime number.

So, Prime numbers in 2 to 10 = {2,3,5,7} =4

So, fraction of prime numbers = $\frac{4}{9}$

Hence there are 9 natural numbers from 2 to 10 and fraction of prime number is $\frac{4}{9}$
