The decimal point separates the places larger than 1 from those that are fractions of 1, such as tenths, hundredths, etc.
Step-by-step explanation:
Decimal Point is a point represented as a small dot is used to separate the whole number part from the fractional part of a number that is, decimals.
Example: in the number 4.9 the point separates the 4 (i.e the whole number part) from the 9 (i.e the fractional part, which really means 9 tenths). So 4.9 is 4 and nine tenths.
