Question 484973
<pre>

    -0.511  <  -0.51

-0.511 is farther to the left on the number line than -0.51

One way to remember it is to think of a °F (or °C) symbol after them:

-0.511°F is a LOWER temperature than -0.51°F, so -0.511 is a LOWER
number than -0.51.

and you can say:

-0.51°F is a HIGHER temperature than -0.511°F, so -0.51 is a HIGHER
number than -0.511.
