Answer 2

Prime Factors can be determined by fraction methods such as LCM and HCF.

Step-by-step explanation:

We've been told that if the denominator of a fraction has factors other than 2 and 5, we need to figure out what kind of decimal expansion it has.

Consider the following examples:

(i)120=12×2×5=0.05

The elements of the denominator are 2 and 5 in this case. The decimal equivalent of the result is 0.05. As a result, we can observe that the decimal point is reached in this example.
