Hey there!
By comparing the numbers, I'm supposing that you're asking which would be greatest as to high and low.
2.43 would be closer to 2.50 -- as 2.50 would be closer to 3.0, which is a whole it's self.
2.34 would be closer to 2.40, which does not reach 2.50, which makes 2.43 greater than 2.34.
2.34 < 2.43
