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 [tex] 153 = 3^2\cdot 17 [/tex]
So, a 3 appears in both numerator and denominator. We can simplify it:
[tex] \cfrac{3}{153} = \cfrac{3}{3^2\cdot 17} = \cfrac{1}{3\cdot 17} = \cfrac{1}{51} [/tex]
If you want to compute the approximated value of this fraction, simply plug these values into some calculator to get
[tex] \cfrac{1}{51} \approx 0.0196078431372\ldots [/tex]
3 ÷ 153 = 1 ÷ 51 = 0,020 aprox.
