Which two letters help you tell the place names on the right of the decimal points from the place names on the other side?

The two letters that help differentiate the place names on the right of the decimal point from those on the left are "c" and "d." The letter "c" typically represents the "cent" or hundredths place, while "d" stands for "decimal" or tenths place. This distinction helps indicate the value of the numbers in relation to the whole number.
