Question

A culture of 1.75×10^18 bacteria is in petri dish A. A culture of 6.25×10^15 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, in the box.

Answer 1

Dividing:- (1.75 * 10^18) / (6.25 * 10^15)

= (1.75 / 6.25) * (10^18 / 10^15)

= 0.28 * 10^3

= 280 Answer
