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

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^m5ⁿ, 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^m5ⁿ,  will have terminating decimal expansion.
