               1  Convert these lengths into the units shown.
                  a  75 mm =   cm        b  1.2 km =   m    c  120 cm =   m
               2  Convert these masses into the units shown.
                  a  2000 kg =   t       b  3.2 kg =   g    c  0.25 t =   kg
               3  Convert these capacities into the units shown.
                  a  8000 ml =   l       b  4.2 l =   ml    c  650 ml =   l
               4  Write these decimal measurements in order of size, starting with the smallest.
                  a  325 m, 850 cm, 0.2 km                  b 3.6 l, 880 ml, 0.7 l
