is -​

Answer 1

Answer:

12:13

Step-by-step explanation:

We need to find the ratio of even digits to the odd digits between the natural numbers from 1-25

As we know that there are a total of 25 integers from 1-25

And both starting and end digits are odd

Therefore there must be odd digits more than even digits

So here are 12 even and 13 odd digits

Hence the ratio will be

$12:13$

Answer 2

To find,

The ratio of even numbers to odd numbers in a set of natural numbers from 1 to 25.

Solution,

Odd numbers from 1 to 25 are : 1,3,5,7,9,11,13,15,17,19,21,23,25

There are 13 odd numbers from 1 to 25.

Even number from 1 to 25 are : 2,4,6,8,10,12,14,16,18,20,22,24

There are 12 even numbers from 1 to 25.

The ratio of even numbers to odd number in a set of natural numbers from 1 to 25 : $\dfrac{12}{13}$ or 12:13. Hence, this is the required solution.
