1. The problem is to show that 180000 is greater than another number, which we will call $x$. 2. The inequality to prove is: $$180000 > x$$ 3. To demonstrate this, we need to know the value of $x$ or have some information about it. 4. If $x$ is given, compare it directly to 180000. 5. If $x$ is unknown, you can only state the inequality as is, or provide conditions under which it holds. 6. For example, if $x = 150000$, then: $$180000 > 150000$$ which is true because 180000 is larger. 7. Without a specific $x$, the statement remains an inequality to be checked with a given number. Final answer: To show 180000 is greater than another number $x$, verify that $x < 180000$.
