Question

Is 4.05 greater than 4.2

Answer 1

no
4.2 is greater than 4.05
basically 4.2 is 4.20 and so 4.05 is smaller

Answer 2

No, 4.05 is not greater than 4.2.

Easier way to look at this is: since both are b, just look at the decimals. For eg, 4.05 becomes 0.05 or 5 and 4.2 becomes 0.2 or 20, and since 20 is bigger than 5, so is 4.2.
