# Without performing the actual division, check whether the following rational numbers are terminating or non-terminating .

Hint:

**Hint:**

Numbers with a fixed or finite number of digits following the decimal point are known as terminating decimals and numbers with infinite decimal places are known as non-terminating decimals.

## The correct answer is: terminating decimal expansion

### Let x = p/q be a rational number such that the prime factorisation of q is in form 2^{m}5^{n}, where m and n are non-negative integers, then x will have a terminating decimal expansion.

c)

x =

In the given rational number, the value of q is 40. The factorisation of 40 is given as

Final Answer:

As the factorisation of 40 is not in the form of 2^{m}5^{n}, will have terminating decimal expansion.
