Change part of date format

Hello!

I am a beginner when it comes to creating formulas in Excel.

I have a column which consists of date and time in the same cell.

Original data:
2015-07-25 00:00:00 UTC

What I am trying to do is come up with a formula to change the date format to MM/DD/YYYY and not use the time stamp at all.

New format after formula:
7/25/2015

Any insights will be much appreciated!

Thank you so much in advance!

Carol
