If they have whole numbers before the decimal point, it's easy. The one with the greater

whole number before the decimal point is the greater number.

If neither one has a whole number before the decimal point, then look for the first place

after the decimal points where their digits are different.

If one has more digits than the other, then zeros can be added to the right of the rightmost digit, without changing the value. The number with the greater digit in that place is the greater number.

Example: compare .09 and .15 : The first digit that is different is 0 and 1. 1 > 0 so .15 is greater.

How about .2 and .23 ? The first digit is 2 in both, .2 doesn't have any more digits, so make it .20, then compare 0 and 3, so .23 is greater.
