Answer 2

Answer:

Decimal Expansion

A decimal is any number in our base-ten number system. A decimal point is used to separate the units place from the tenths place in the decimal. A decimal point is also used in currency to separate the dollars from the coins. For example, if I say a certain pen costs $1.30, what I mean by that is that the pen costs 1 dollar and 30 cents.
