Answer:
-13F is less than<em> </em>-12F, and -9F is greater than -12F
Step-by-step explanation:
You can prove this because in the problem is states that -13F < -12F < -9F
If you utilize this, you find that the first statement is quite obvious:
-13F is less than -12F
The second statement is a little trickier. Since in the original inequality is states that -12F < -9F, but you want to know the relationship between the switch, you would just flip the sign in the middle, getting you:
-9F is greater than -12F
You could also prove this simply with the rules of negative values (which work inversely from positives).
