1. KBrO3 is a salt soluble in water that ionizes 100%; ie.,
..........KBrO3==> K^+ + BrO3
I.........0.01.....0......0
C........-0.01....0.01....0.01
E..........0......0.01....0.01

.........AgBrO3 --> Ag^+ + BrO3^-
I........solid......0......0.01
C........solid......x.......x
E........solid......x.....0.01+x

Then Ksp AgBrO3 = (Ag^+)(BrO3^-)
Look up Ksp and substitute the E line into Ksp expression and solve for x = (Ag^+).
