Ubuntu – Expand root partition without formatting


I would really like a clear guide to expand my root (/) partition. The screenshot shows my partitions (Windows 7/Ubuntu 14.04 – dual boot) and as you can see /dev/sda3 is my Ubuntu partition. I would like to move the 90 GB unallocated partition up to the root and expand the root. I would appreciate help with the following questions:

  1. Can I freely resize the data partition (/dev/sda5) until it has no more unused space?
  2. Can I even extend the root without formatting it?
  3. Can I unmount (so that i may move the 90 GB up) the home partition without bad stuff happening?

My partions:
