How to add scale (not scale bar) to a layout?

[ViktorSafar]

I can get the value from the map and put it into a text element. But that will require me to write more logic handling the scale changes. Is there a component I can use?

You can create a Dynamic Text element to write out the Map Frame's scale. 

var layout = LayoutView.Active.Layout;
if (layout == null)
  return;
//Construct the dynamic text string.
//You can create the dynamic text in the UI to get a hint as to how to compose the string in code.
String title = @"Scale: <dyn type=""mapFrame"" name=""Map Frame"" property=""scale"" preStr=""1:""/>";
Coordinate2D llTitle = new Coordinate2D(6, 2.5);
await QueuedTask.Run( () => {
  TextElement titleGraphics = ElementFactory.Instance.CreateTextGraphicElement(
                layout, TextType.RectangleParagraph, llTitle.ToMapPoint(), null, title) as TextElement;
});
