# Math Help - Compute

1. ## Compute

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 $1\frac{7}{40}$

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

Therefore, the test answers are incorrect? Why is from the compass sample questions...

Ask THEM, not us...
