Classify each number according to its value 

2.1x10^-4

8.3x10^-5

9.2x10^-4

2.1x10^-3

7.2x10^-5

2.8x10^-7

3.4x10^-5

 

Greater than 8.2x10^-4

Between 8.2x10^-4 and 8.2x10^-5

Less than 8.2x10^-5

 

Thank you all sosososo much and sorry it's not it latex. Something was really weird with it and it wasn't working, but I hope this works too! Thank you again.....hopefully i made no typos.........

The bigger the power of 10 is then bigger the number is.

             Assuming it is multipled by a number between one and 10 (scientific noatation)

 

So looking at the first one

2.1x10^-4     

 

2.1 is between 1 and 10 so  this number is in scientific noation.  (All of them are in scientfici notation.)

 

Any number in scientific noation with a power of 10 less than -5 will be less than that one.

Si it is definitely noNOT Less than 8.2x10^-5

Is it Greater than 8.2x10^-4    Well they hae the same power, but 8 .2 is bigger than 2.1 so NO

 

Is 2.1x10^-4   Between 8.2x10^-4 and 8.2x10^-5 ?

Why do't I put the little one first ...    Is it Between 8.2x10^-5  and 8.2x10^-4 

Its bigger than the little one and smaller than the big one so it has yo be between them!

 

You can do the others yourself.

If you want to discuss you answers/working that is fine.

It would be sensible to write them in order from smallest to largest then you will not have to think about the final comparisons so much.
