Question

How do you multiply `825.6\times 0.004`?

Answer 1

`825.6xx0.004=3.3024`

Explanation:

From the definition of decimal `825.6=825+6/10=8256/10`

and `0.004=0+0/10+0/100+4/1000=4/1000`

Hence `825.6xx0.004`

`=8256/10xx4/1000`

`=(8256xx4)/10000`

`=(33024)/10000=3+3/10+0/100+2/1000+4/10000`

`=3.3024`
