Answer 2

Answer:

The smallest rational number by which 31 should be multiplied so that its decimal expansion terminates aft er one place of decimal is 1/10

Step-by-step explanation:

$31\times\frac{1}{10} =3.1$

Thus among the given options it seems 1/10 is the number that when multiplies by 31 will give the number 3.1 which terminates after one place of decimal. 1/10 is a rational number because 1 is an integer and 10 is also an integer and it is written in the form of p/q.
