Briefly describe how to show the same formatted placeholder on multiple slides by customizing the slide master.

What will be an ideal response?

You can customize a theme's slide master to insert a customized placeholder into a slide layout. Using a slide master saves you time because you do not need to customize the placeholder manually on each slide. The slide master is useful when you have extremely long presentations. Every document theme has several slide masters that indicate the size and position of text and object placeholders. Any change you make to a slide master results in changing that component in every slide of the presentation.
