A certain corporation listed their sales in 100s as 20700. What was their actual volume in millions?

Mariana [72]

Answer: Their actual volume in millions is 207×10⁹.

Step-by-step explanation:

Since we have given that

A certain corporation listed their sales in 100s as 20700

We need to find their actual volume in millions,

According to question,

In 100s, their volume = 2070000

In 100000, their volume is given by

$207\times 10^5\\\\=2070000\times 10^5=207\times 10^9$

Hence, their actual volume in millions is 207×10⁹.
