**Reiny**, Tuesday, October 23, 2012 at 11:29amyour numbers were probably written as

2.5 x 10^7

which means 2.5 x 10000000 , notice 7 zeros from 10^7

= 25 000 000 --> 25 million

do the same with the other numbers and you will be able to compare their sizes.

8.57 x 10^-4

= 8.57 x 1/10^4

= 8.57 x 1/1000 -----> count the zeros in the denominator

= .000857 -----> how many places to the left has the decimal moved?

does that give you any hints for quick solutions to these kind of problems?
