What is the answer of 7 copies of the sum of 8/5 + 4

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)
