Rational positive numbers
Rational numbers because it can be expressed as a fraction
The number 0.12123123412345 belongs to the set of real numbers, specifically as a decimal representation of a rational number if it can be expressed as a fraction. Additionally, it can be classified as an irrational number if it does not terminate or repeat, but in this case, it appears to terminate after a certain point, suggesting it is likely a rational number. Thus, its set of belonging includes rational numbers, real numbers, and decimal numbers.
Rational because it can be expressed as a fraction in the form of -50/1
Pi, and the square root of pi, belong to a category known as transcendental numbers, which means that not only do they have an infinite decimal expansion (the numbers following the decimal go on forever) but the decimal expansion follows no pattern and is unpredictable. Irrational numbers also have an infinite decimal expansion, but not necessarily an unpredictable one.

I'm just telling you this ahead of time...but i'm not 100% sure with this answer..: fractions belong in the Rational Numbers
The number 0.12123123412345 belongs to the set of real numbers, specifically as a decimal representation of a rational number if it can be expressed as a fraction.

Thus, its set of belonging includes rational numbers, real numbers, and decimal numbers.
It belongs to the set of negative rational numbers, negative real numbers, fractionall numbers, rational numbers, real numbers.
Integers are all of the positive and negative whole numbers, and zero. Integers are not fractions or decimal numbers.Integers are the class of whole numbers, such as 21, 3, -45. Fractional or decimal numbers do not belong to this class.- 5 + 8 - (- 4)
A mixed fraction is a rational number because you can rewrite it as one integer over another.

Negative fractions are part of all of the following sets, and a few more:Complex numbersReal numbersRational numbers (assuming you are talking about a fraction with integer numerator and denominator)
Pi, and the square root of pi, belong to a category known as transcendental numbers, which means that not only do they have an infinite decimal expansion (the numbers following the decimal go on forever) but the decimal expansion follows no pattern and is unpredictable. Irrational numbers also have an infinite decimal expansion, but not necessarily an unpredictable one.
The set of numbers which 3 does not belong is the set of even numbers.
The number 1.68 belongs to the subsets of real numbers known as rational numbers and decimal numbers. As a rational number, 1.68 can be expressed as the ratio of two integers (84/50). It is also a decimal number, specifically a terminating decimal, where the digits after the decimal point eventually end.
