In my opinion, check of work would be:Hi Redmoon. I'm guessing that you meant to type 3 and 11/56.
Yes, [imath]3\frac{11}{56}[/imath] is the correct answer, and your work is good.
Here's a way to check your result. Google each of the following (or use a calculator with built-in grouping symbols) and compare the decimal results.
(5+4/7) – (2+3/8)
3+11/56
Cheers ?
[imath]\;[/imath]
(3+11/56) + (2+3/8)
= (3+2) + (11/56 + 3/8)
= (5) + [11/56 + (3*7)/56]
= 5 + (32/56)
= 5 + 4/7 [checks]
Now where is my piece of cake ???
