Question

a culture of 2.4 x 10^11 bacteria is in petri dish. A culture of 8×10^9 bacteria is in petri dish B. how many times greater is the number of bacteria in a petri dish A than petri dish B? enter your answer, in standard notation down below

Answer 1

2.4×10¹¹=240000000000
8×10'9= 8000000000
240000000000÷8000000000=30
so A is ×30 greater that B

Answer 2

2.4×10¹¹=240000000000

8×10'9= 8000000000

240000000000÷8000000000=30

so A is ×30 greater that B
