18cm%3A8m+=18cm%2F8m

to simplify this ratio, convert either cm to m, or m to cm

1m=100cm or 1cm=0.01m

so,

18cm%2F8m

18cm%2F800cm...divide both numerator and denominator by 2

cross%2818%299cm%2Fcross%28800%29400cm

9cm%2F400cm

OR if you take 1cm=0.01m, you will have

18%2A%280.01%29m%2F8m

0.18m%2F8m

0.9m%2F4m
