what is the rule for greater than less than sign.

The greater than sign, > , means that whatever is to the left of it is greater than what is to the right of the sign.
The less than sign, < , is just the opposite. Whatever is to the left of the sign is less than what's on the right.
It should be noted that when a number is greater than another, then the greater one is to the 'right' of the other number on the number line, so it's just the opposite of how we read the symbol. That is, a>b if and only if a is to the right of b on the number line. This is sometimes given as the definition of '>' with less than being just the opposite of this: a<b if and only if a is to the left of b on the number line.

Pacman eats the bigger number

3 < 8
5 > 2

One other way to look at it is that the sign always points to the lower number. Take note that the less than sign looks like a crooked L.
