Rate Laws question- check my reasoning!

Give the individual reaction orders for all substances and the overall reaction order from the following rate law:

Rate = k [O3]^2/[O2]

I'm having trouble interpreting this question. It's the first time I've seen a rate law with a denominator. Would the overall order be 1, and the order of [o3] 2, and the order of [o2] 1?
