Heterozygous inversion test cross

Below is a map of the Drosophila melanogaster X chromosome, giving the distances between adjacent genes in centiMorgans.  
 
sn-----------------lz------------v----------wy-----------m-------s------g
   6.7            5.3         3.2          4.5        2.3    1.4


Suppose that a female is heterozygous for an inversion of the exact entire region from v to wy.  
She is also heterozygous for all the genes shown in the map, and is test-crossed.  
What percentage of her progeny will be recombinants between the following gene pairs?

a) sn and lz ____________

b) lz and m _____________
