2. 1/5 or 20/100

Answer 2

Step-by-step explanation:

Part-1

Well, let’s count the number of square numbers.

1, 4, 9, 16, 25, 36, 49, 64, 81, and 100

So, that gives us 10 square numbers, out of 100 numbers.

So, 10/100 = 1/10.

part-2

Well let's count number which are divisible by 5.

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, and 100

So,that gives us 20 numbes, which are divisible by 5

So, 20/100 = 1/5
