Can I use my wireless iMac keyboard with my iPad Pro?

I Have the iPad Pro (WiFi only) with iOS 9.2.1 purchased in Dec. 2015 and an iMac with iOS 9.2.1 purchased in August 2015. The iMac came with a wireless keyboard (no 10 key pad) and I want to know if there is a way to use this keyboard with my iPad. I am currently using the built in touch keyboard but would like to use a real keyboard with my iPad. I know I can buy the keyboard for the iPad Pro for $169.00 but would like to know the answer to this question before entertaining the thought of buying another accessory.

Thanks,

Judy
