Answer explanation

We must convert percents to a "regular" number. If we divide by 100 or move the decimal 2 spots left, we get the number 3.

3 ends making it rational.

3 is not a decimal making it an integer.

3 is positive making it whole.

3 is a counting number, making it natural.

The farthest circle in that 3 belongs to is natural.
