84/5-5 1/10= 3 7/10.
You have to make both numbers into improper fractions, so 8 4/5 becomes 44/5 (8*5+4) and 5 1/10 becomes 51/10 (10*5+1).  Next, You have to get a common denominator, which will be 10.  Multiply the top and bottom of 44/5 by two, and you'll get 88/10.  Now you can subtract 88/10-51/10 to get 37/10.  This can be reduced to 3 7/10.

Hope this helped!
