A package of dental floss contains 25 m of floss. How many yards of floss are in the package? If a dental hygienist uses about 18 in. of floss for each patient, how many patients can be cleaned with one package of floss?
Twenty five meters converted to yards is 27.34. For the second bit, 18 inches is 1.5 feet so we divide 27.34 by 1.5. He will be able to floss 18 patients.
