Question

solve this question and please give me reason for answer​

Answer 1

q must be factor only 5 or 2 or both it is a theorem

Answer 2

Answer:

q must only have 2 or/and 5 as its factors

Step-by-step explanation:

if we take an example of the fraction 13/20

so if we write this fraction with its numerator and denominator in the form of their factors... now it can be written as 13/5*2*2

and now if we multiply this fraction by 5/5   it will become 65/100 which can be seen as simply a terminating decimal number i.e 0.65

But if were to take a fraction as 16/35

and write it in its factor form i.e   2*2*2*2 / 7*5

and even if we multiply it by 2/2 it will still be 32/70 i.e 3.2/7 and will thus be non terminating
