Answer:
5 1/12
Step-by-step explanation:
Your calculator will give you the repeating decimal ...
5 +11/12 -0.375 = 5.08333...(repeating 3)
If your calculator can convert this to a ratio of integers, you will get ...
= 61/12 = 5 1/12
__
You should recognize 0.375 as being the decimal equivalent of 3/8. Then the mixed-number arithmetic is ...
5 11/24 -3/8 = 5 11/24 -9/24 = 5 2/24 = 5 1/12

Additional comment
Many scientific and graphing calculators can do arithmetic with mixed numbers, and can convert between decimal and mixed-number formats. It might be worthwhile to get one. There are apps for phone and tablet that will do this, too.
