If the fraction d were converted into a decimal, would there be more than 3 nonzero digits to the right of the decimal point?

(1) The denominator of d is exactly 8 times the numerator of d.
(2) If d were converted into a decimal, d would be a non-repeating decimal.

If the fraction d were converted into a decimal, would there be more than 3 nonzero digits to the right of the decimal point?

Let $$d=\frac{x}{y}$$.

(1) The denominator of d is exactly 8 times the numerator of d. Given that $$y=8x$$, thus $$d=\frac{x}{8x}=\frac{1}{8}=0.125$$. Sufficient.

(2) If d were converted into a decimal, d would be a non-repeating decimal. Clearly insufficient, for example d could be 0.1 or 0.1234. Not sufficient.

Thanks bunuel - but is 0.1 a non repeating decimal?

I am actually confused & assumed pie (3.14...) as my example and marked D.

We are told that "If d were converted into a decimal, d would be a non-repeating decimal", thus 0.1 and 0.1234 are valid examples.
