Final answer:
Any number greater than 2.1 is a solution to the inequality b > 2.1. Examples include 2.2, 3, or 10.0, as they all satisfy the condition of being greater than 2.1.
Step-by-step explanation:
The question is asking to find a number that is a solution to the inequality b > 2.1. In mathematics, an inequality specifies the relative size or order of two objects or, it could refer to a wide range of mathematical expressions that show that an expression is less than, greater than, or simply not equal to another expression.
Since the inequality given is b > 2.1, any number that is greater than 2.1 will satisfy this condition. There is an infinite number of possible solutions to this inequality because any decimal or whole number larger than 2.1 will work.
An example of a number that is a solution to the inequality would be b = 2.2, b = 3, or even b = 10.0, as all these values are greater than 2.1.
