Ivanshal [37]
In order to list the measurements from smallest to largest, we convert all the measurement to a common unit. In this item, we convert the given to meters, m.

A. The conversion factor to be used here is 1 m = 100 cm
      (7 cm)(1 m / 100 cm) = 0.07 m

B. Conversion factor: 1 m = 1000 mm
     (18 mm) (1 m / 1000 mm) = 0.018 m

C. Let us list this as is, 1 m

D. The conversion factor here is 1 m = 10 dm
    (3 dm)(1 m / 10 dm) = 0.3 m

By the converted values, we are then able to arrange the given measurements.Hence, the arrangement should be 18 mm, 7 cm, 3 dm, and 1 m.
