A culture of 2.4×10^11 bacteria is in petri dish A. A culture of 8×10^9 bacteria is in petri dish B.
How many times greater is the number of bacteria in petri dish A than petri dish B?
Enter your answer, in standard notation.
A / B =
[2.4 x 10^11 ] / [ 8 * 10^9 ] =
[2.4 / 8 ] * [ 10^11 / 10^9 ] =
.3 * 10^2 =
30 times as great
