Okay, it's been a few years since I've had to use Excell and I'm terrible at math :(

my boss wants to know the total percentage for 2013 of our interplant and warehouse shipments.

The total number of shipments for those are: 4,297

The number of cuts are: 5311

What formula should I use to find this percentage of cuts against these shipments?

Thanks guys, I'm so stupid it hurts sometimes
