Mary used 14 meters of ribbon to make bows and strips. she used 3/4 as much ribbon for bows as she did for strips. how many meters of ribbon did she use for bows and how many for strips?

total = 14 m.
ratio of bows:strips = 3:4
Length for bows = 3/(3+4)*14=6 m
Length for strips = 4/(3+4)*14=8 m

Check: 6m + 8m = 14 m = total, ok.
