Quite simple, actually...
so...just simplify all of these numbers...
7.25%=0.0725
7.25*10(-3)--->>7.25*-30....
=-217.5
7 1/4..it's not that hard to change this one.. the [tex] \frac{1}{4} [/tex] is really 0.25, or...
7.25
and finally,
0.725
So, we have...
0.0725,-217.5,7.25 and 0.725
Now, looking at them, they are really easy to see least to greatest...
-217.5, 0.0725, 0.725, and 7.25.
Thus, your answer.
