8m, 9 cm = 809 cm
number of pieces which are 9 cm long
= 809/9 = 89.88.. or appr 90 cm each
btw,
in the true usage of the metric system, one would not say
8m, 9cm
it would be either 809 cm or 8.09 m
the beauty of the metric system is that you don't have to mix units like in the old imperial system.
