Question

Arrange the following length in their decreasing.
1 metre,0.5km,400 dm,100mm

Answer 1

In decreasing order, (converting all units to metre)

1m=1000mm=100mm=0.1m

1km=1000m,0.5km=500m

10dm=1m,400dm=40m

1m, as it is

So , 500m > 40m > 1m > 0.1m

Finally , 0.5km > 400dm > 1metre > 100mm

Final Answer

I hope that it will help you
