Rule: Any positive number is always larger than any negative number.
For example, 10 is larger than -2. So we write 10 > -2.
The same goes for 8 & 1/4 vs -8 & 1/4. It doesn't matter if we involve fractions or decimals.
Visually, positive numbers are to the right of 0 on the number line. Negative numbers are to the left of 0.
Stuff on the right is larger than stuff on the left.
