Question

Name any two multiples and sub-multiples of metre and show their relationship.

Answer 1

1. For measuring some length or distance, we use the unit metre.
2. The SI unit of length is metre.
3. When we have to measure the larger distance, we use multiple of metres
   $1$ $\text{decameter}$$=10\text{m}$
   $1\mathrm{k}\text{ilometre=1000m}$
4. When we have to measure a smaller distance, we use sub-multiples of metre.
   $1\mathrm{d}\text{ecimeter=0.1m}$
   $1\text{centimeter=0.01m}$
