In this investigation paper, we present some weighted inequalities Newton-type for various classes of functions utilizing Riemann–Liouville fractional integrals. The study begins by introducing a positive weighted function to derive a key integral equality essential for proving the main results. By applying this equality along with Riemann–Liouville fractional integrals, we establish several weighted Newton-type inequalities for some function classes, including Lipschitzian functions, bounded functions, convex functions, and functions of bounded variation. The results offer valuable insights into the significance of inequalities of Newton-type and give some directions for future research. The findings extend those presented in earlier works.
