Answer:
You have completed only half in a 1/4 of a day
Step-by-step explanation:
think of it this way
lets say in half a day e.g at 12pm you finish the report
half of 12 is 6
so that would be a 1/4 of the day
100%=24 hours=whole day
50%=12 hours=half a day
25%=6 hours = quarter of a day
25% = 1/4
i hope this helps
