Answer 2

If you're looking for the simplified version of the fraction, you have to factor both numerator and denominator.

The numerator is actually already a prime number, so we're good

The denominator factors as $153 = 3^2\cdot 17$

So, a 3 appears in both numerator and denominator. We can simplify it:

$\cfrac{3}{153} = \cfrac{3}{3^2\cdot 17} = \cfrac{1}{3\cdot 17} = \cfrac{1}{51}$

If you want to compute the approximated value of this fraction, simply plug these values into some calculator to get

$\cfrac{1}{51} \approx 0.0196078431372\ldots$
