Answer 1

Explanation:

Multiples and submultiples are prefixes and sufixes that is used to express scientific quanties.

deci = 10^-1

centi = 10^-2

mili = 10^-3

micro = 10^-6

nano = 10^-9

pico = 10^-12

femto = 10^-15

atto = 10^-18

These are submultiple.

The SI unit of lenght is metre. When a larger distance is to be covered, we cannot use metre. So to cover a larger distance we use km(kilometre) , hm (hectometre) , and dac(decametre). These are called the multiples of Metre. When the distance is smaller , we use Dm (decimetre , cm(centimetre) and mm (millimetre) . These are called the submultiples of Metre.
