Percentage of homework that is left to be completed = 65%
Then
The percentage of homework that is already done = (100 - 65) percent
= 35 percent
= (35/100)
= 7/20
= 0.35
So the amount of homework that has already been completed can be represented as 7/20 or o.35. Hope this is the answer you were looking for and i have helped you in this matter. Also i hope the procedure is easy enough for you to understand.
