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?
$56\over 90$ of the allotted time remains.
How much of the task remains depends on how fast you work.
