Which statement is true?

-2.4<-2.40

-2.4≠-2.40

-2.4≤-2.40

-2.4>-2.40

The last one is true

-2.4 < - 2.40

This is false because they are equal to each other/they are the same number. So - 2.4 can't be less than - 2.40.

-2.4 ≠ - 2.40

This is false because they are equal to each other, as they are the same number.

-2.4 ≤ - 2.40

This is true because - 2.4 is equal to - 2.40

-2.4 > - 2.40

This is false because they are the same number, so - 2.40 can't be less than - 2.4.

The third choice is your answer.
