The question looks to be incomplete (without the appropriate choices). But still answering related to the inequalities part:
Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥ and ≠.
[tex]7 \textgreater x[/tex] reads as '7 is greater than x' (or ' x is less than 7', reading from right to left). Here above, Statements are equivalent when both sides are true or logically the inequality holds good here.
We have , -2.5<8/13 . which is equivalent to -2.5< 0.615 which holds true. We know that any negative number is always smaller than any positive number, also less than 0. And , -2.5 value is less than 0.615. ∴ Inequality holds good!
