Answer 1

The number 2.25 falls into the number groups of Real Numbers and Rational Numbers. It does not belong to Integers, Irrational Numbers, Natural Numbers, or Whole Numbers.

Step-by-step explanation:

Number groups or sets classify numbers based on their properties. 2.25 falls into specific number groups. Firstly, it does not fall into Integers, Natural Numbers, or Whole Numbers, since these groups consist only of non-negative numbers without fractions or decimals.

However, 2.25 is a Real Number because it is a value that represents a quantity along a continuous line of numbers.

Furthermore, 2.25 is a Rational Number because it can be expressed as a fraction (¾), where both the numerator (9) and the denominator (4) are integers. It is integral to note that Irrational Numbers cannot be represented by a fraction of two integers.
