Mr.Keith,
The answer to this problem is 4. I got the answer 4.4444444444444444444 so I rounded to the nearest whole number so I received 4.

Mr.Quinn,
I think the answer to this problem is 4 because you round down when you get 4.444444444444, but I think is uncorrect ma'm.

Damon,
4*10^9

1.2 * 10^7
is
400 * 10^7

1.2 * 10^7
is
400/1.2
or
333 times as many
