if you notice 0.2 --> 1/5
to make it comparable to 1/25, notice that five 1/25 = 1/5
there are 5 fractions but they all become incrementally smaller than 1/5 so they will be less than five 1/25 making QB> QA

Notice how the first fraction , the result, is 0.04
Now, the more the numerator is constant and the denominator increases, then we will have a minor fraction
Therefore, we will have a fraction even smaller 0.03 ....
B is the answer
