How do I arrange these from greatest to least? -4.29 x 10^-5
-1.370 x 10^6
-9.3 x 10^-2

-4.29 x 10^-5, -9.3 x 10^-2, and then the least is -1.370 x 10^6

Explanation:

Now use common sense.

-0.093 is the greatest number.

Then -429,000 is in the middle.

Lastly, -1,370,000 is the least number.

Why?

Because as a negative number gets bigger, the more least the number is. It is the opposite of positive numbers. For positive numbers, as a number gets bigger, the more greater the number is. That is a rule.
