In this paper, we study inhomogeneous Diophantine approximation with rational numbers of reduced form. The central object to study is the set $W(f, heta)$ as follows, egin{eqnarray*} left{xin [0,1]:left |x-frac{m+ heta(n)}{n}
ight|<frac{f(n)}{n} ext{ for infinitely many coprime pairs of numbers } m,n
ight}, end{eqnarray*} where ${f(n)}_{ninmathbb{N}}$ and ${ heta(n)}_{ninmathbb{N}}$ are sequences of real numbers in $[0,1/2]$. We will completely determine the Hausdorff dimension of $W(f, heta)$ in terms of $f$ and $ heta$. As a by-product, we also obtain a new sufficient condition for $W(f, heta)$ to have full Lebesgue measure and this result is closely related to the study of ds with extra conditions.
