If Sean had 1.0 * 10^7 jelly beans and Jeremy had 4.0 * 10^4 jelly beans, how many times greater was Sean's collection compared to that of Jeremy?

Sean's collection was 250 times greater than Jeremy's.

Step-by-step explanation:

1.0 x 10^7 is the same as 10,000,000

4.0 x 10^4 is the same as 40,000

Divide 10,000,000 by 40,000 to get the answer. 10,000,000/40,000 = 250
