Theory:
Number can be expressed in two forms fractional notation and decimal notation.
Fractional representation is a way to express numbers that fall in between integers (note that integers can also be expressed in fractional form). A fraction expresses a part-to-whole relationship in terms of a numerator (the part) and a denominator (the whole)
The decimals has ten as its base. Decimals can be terminating (ending) (such as 0.78, 0.2) or repeating (recurring).Decimals can be terminating (ending) (such as 0.78, 0.2) or repeating (recurring).
