Question

How many times greater is 8.5×108 than 3.4×105 ?

Answer 1

8.5*108=918
3.4*105=357
918/357=2.57143

Answer 2

2.5*10^3 times greater, or 2500 times greater.

Explanation:

Dividing 8.5*10^8 by 3.4*10^5 will yield the desired answer (which is a ratio). Note: 108 and 105 MUST be written with the symbol " ^ " to denote exponentiation.

8.5*10^8

--------------- = (8.5 / 3.4)*10^(8-5) = 2.5*10^3

3.4*10^5
