Maybe like this:

ax.annotate('Time = %f'%(MBH_inst[0],), size=18, xy=(3, 1),  xycoords='data',
            xytext=(0.8, 0.95), textcoords='axes fraction',
            horizontalalignment='right', verticalalignment='top',
            )
?

You can also adjust the number of shown digits right of the comma by setting 
it up like this: %0.2f etc.

Just look it up in the python documentation (search hints: python string 
format).


Wish you the best,
