The larger number will be -4.03
For negative numbers, I like to sort of think backwards as I would when looking at positive numbers. For example:
+4.3 > +4.03
But when it is negative it will be the opposite!
-4.3 < -4.03
The “larger” the negative may seem, the smaller it actually is! Think of it on a number line!
Hoped this helps you out! Have a good day!
