the bloodhound has 4.0*10^9 scent receptors in its nose. a typical human has 1.2*10^7 scent receptors.
how many time more scent receptors does a bloodhounds have than a human? round answer to the nearest whole number

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.

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.

4*10^9

1.2 * 10^7
is
400 * 10^7

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