To solve (8/5 + 4)7, you first have to add 8/5+4.  But you cannot simply add the too because they have to be in a common denominator 'form'.  To do that, we find a common denominator which is 5.  We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28.  You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1.  Another of saying 28/5 is 5 3/5.  So 5 3/5 x 7/1= 39 2/10 (final answer)
