Compute: 3/8 + 4/5

I don't understand this questions, is from my placement test, I solved it but it's not a choice of the test. Is it trying to fool me? or am I fooling myself.

My answer: 47/40 or $\displaystyle 1\frac{7}{40}$

CHECK it YOURSELF (use a calculator!):
3/8 + 4/5 = 1.175
47/40 = 1.175
