I would change each mixed fraction as follows to a fraction:
5 7/16 = (5*16)+7 = 87/16
4 1/19 = (4*19)+1 = 77/19
9 3/17 = (9*17)+3 = 156/17
Then find the lowest common decnominator and go from there.

When all else fails, you can always use 16*17*19. That may not be the lowest but it will always work. The final answers may be reducible.
