Question

George and veronica are both musicians who sell their sogn online during the same year George sold 8x10^5 download of his song and veronica sold 4x10^6 download of her songs. how many time as much is there of song that veronica sold than the number of song that George sold?a.2 b.5 c.20 d.40

Answer 1

George sold:

$\begin{gathered} 8\times10^5 \\ =800,000 \end{gathered}$

and Veronica sold:

$\begin{gathered} 4\times10^6 \\ =4,000,000 \end{gathered}$

As expanding the scientific notation numbers, we see that

George sold eight hundred thousand

Veronica sold 4 million

How many time is 4 million of 8 hundred thousand?

We simply divide!

$\frac{4,000,000}{800,000}=5$

So,

Veronica's song was downloaded 5 times the numebr of that of George.

B is the right answer.
