Question

Express the following in the form of kilometres using decimal places.
9 m
78 m
825 m
9456 m
25 km 726 m

Answer 1

We know that, 1000 m is equal to 1 km.
9 m = $\frac{9}{1000}$ km = 0.009 km
78 m = $\frac{78}{1000}$km = 0.078 km
825 m = $\frac{825}{1000}$ km = 0.825 km
9456 m = $\frac{9456}{1000}$ km = 9.456 km
25 km 726 m = (25 + $\frac{726}{1000}$) km = (25 + 0.726) km = 25.726 km
