Problem solving involving time

Question

You have from 10 pm to 11:30 pm to do a project. At 10:34 what fraction of the project remains?

I keep getting stuck and I don't know why. There is an hour and a half to do the project and at 10:34 I know there are 56 minutes left to complete the project but what is the fraction?

The first $90%$ of a project takes the first $90%$ of the time. The last $10%$ of the project takes the other $90%$ of the time. — Ross Millikan, Apr 06 '14 at 02:29
It's time remaining/time allotted. So for a 90 minute time box you start with 90/90 (1 x 100 = 100%) and as the time elapses the time remaining decreases. — Ian Lewis, Aug 19 '14 at 11:27

$56\over 90$ of the allotted time remains.

How much of the task remains depends on how fast you work.
