It might look tricky at first, but here's a quick way to compare:
9.11 is the same as 9.110
9.9 is the same as 9.900
So when you compare:
9.110 < 9.900 — nope! That's not right.
Oops — looks like that was a trick! I made a mistake.
Let’s do it right:
9.11 = 9.110
9.9 = 9.900
Now you can clearly see that 9.900 > 9.110, so:
9.9 is actually bigger than 9.11.
Sneaky decimal move, right?
