I'm not seeing the problem. Both widgets move when the window is expanded.
Here is my code, only slightly modified from yours:


########################
import tkinter as tk


class SimpleEntryGrid(tk.Frame):
     def __init__(self, parent, bg_colour="light blue"):
         super().__init__(parent, bg=bg_colour)

         self.enter_label = tk.Label(self, text="enter a number")
         self.number_enter = tk.Entry(self)

         self.enter_label.grid(row=0, column=0,
                               padx=5, pady=5, sticky="nsew")
         self.number_enter.grid(row=0, column=1,
                               padx=5, pady=5, sticky="nsew")


class SimpleEntryPack(tk.Frame):
     def __init__(self, parent, bg_colour="light blue"):
         super().__init__(parent, bg=bg_colour)

         self.enter_label = tk.Label(self, text="enter a number")
         self.number_enter = tk.Entry(self)

         self.enter_label.pack(side=tk.LEFT,
                               padx=5, pady=5, expand=True)
         self.number_enter.pack(side=tk.LEFT,
                                padx=5, pady=5, expand=True)

top = tk.Tk()
seg = SimpleEntryGrid(top)
sep = SimpleEntryPack(top, bg_colour="grey")
seg.pack(side=tk.LEFT, padx=15, pady=10, expand=True)
sep.pack(side=tk.LEFT, padx=15, pady=10, expand=True)

top.mainloop()
