Answer:
James works on history 6/10 of an hour more than on English.
Explanation:
This is because 9/10 - 3/10 = 6/10
James works on history 6/10 more that English.
Since he worked on History for 9/10 of an hour, and worked on English for 3/10 of an hour. He would be working on history 6/10 more than English.
9/10-3/10=6/10.
6/10=3/5
