Answer: 37/40
Step-by-step explanation: using LCM (lowest common multiple) or by simply multiplying 5 x 8, the denominator is 40. In doing so, you would also have to cross multiply 4 x 8 and 5 x 1, making 32/40 and 5/40. Add them both together and you get 37/40, which i believe is in fact in lowest terms. By decimal it would be 0.925.
Hope this helps!
