I was to find the sum or difference of each problem: A) 15.6 + 8.305 + 0.4=
24.305 B) 14/3  16/5= 20/15  18/15=
2/15 C) 20.096  42.3 = 22.204
D) 3 1/8 + 4 5/6 = 25/8 + 29/6=
150/48 + 232/48= 82/48. Is this correct?

It depends whether or not one considers significant digits. If not, then yes correct.

yes
