John write 3 1/20 Documents on FRIDAY
Step-by-step explanation:
John needed to write 12 documents
John Completed 3 1/5 = (16/5) Documents on WednesDay
John Completed 5 3/4 =(23/4) Documents on ThursDay
Let say John Completed D Documents on Friday
16/5 + 23/4 + D = 12
Multiplying by 20 on both sides
=> 64 + 115 + 20D = 240
=> 20D = 61
=> D = 61/20
=> D = 3 1/20
