Are u accessing disk utility in the OS itself?
Can you try accessing Disk Utility in OS X recovery to perform the resize?
I'm thinking you might need to repartition the whole drive as a last resort.
However there are some terminal commands you can try before doing that.
Seeing you have a CoreStorage Volume there, I found the following article you can use as a guide - http://blog.fosketts.net/2012/10/03/mac-os-corestorage-resize/
Good luck!
If you don't want to mess with the terminal commands (as described above), the best way to do it is this:
1. Create a bootable clone of your existing drive to an external drive using either CarbonCopyCloner or SuperDuper.
2. Boot from the external clone.
3. Re-initialize your internal drive into a single partition
4. RE-CLONE from the backup BACK TO the internal drive.
This WILL do the job.

Looks like Yosemite turned your disk into a core storage volume and that stops the resize in Disk Util.
Assuming you only have one disk drive and that is where Yosemite is, run the command below in Terminal to revert the core storage then you will be able to manipulate the partitions normally in Disk Util.
Code:
diskutil cs revert disk1
