a) 37 cm = $\frac{37}{100}$ m
9 dm = $\frac{90}{100}$ m
68 m = $\frac{68}{1000}$ km
804 m = $\frac{804}{1000}$ km
b) 12 m 7 dm = 12$\frac{7}{10}$ m
8 m 3 cm = 8$\frac{3}{100}$ m
17 m 53 mm = 17$\frac{53}{1000}$ m
29 km 4 m = 29$\frac{4}{1000}$ km
c) 875 cm = 8$\frac{75}{100}$ m
7305 mm = 7$\frac{305}{1000}$ m
5034 m = 5$\frac{34}{1000}$ km
36 270 m = 36$\frac{27}{100}$ km
