Question
Write an inequality to represent the following:
Lucy's brother's age is not 24 months.
- a < 24
- a = 24
- a ≠ 24
- a > 24
Hint:
We are given a statement. We have to write the expression of inequality for the given statement. We have to see the limits given for the required value.
The correct answer is: a ≠ 24
The given statement is as follows:
Lucy’s brother’s age is not 24 months.
Let the age be represented using the variable “a”.
Lucy’s brother’s age is not 24 months means, we cannot write the variable equal to 24. We don’t know if the age is greater than or less than 24 but it’s not 24.
So, we will use the sign of not equal to.
The sign for not equal to is "≠"
The mathematical representation of the inequality is as follows:
a ≠ 24
This is the given inequality.
For such questions, we have to be careful about the limits.
