The diameter of a human hair is 9*10^−5 meters. The diameter of a spider's silk is 3*10^−6 meters.

How much greater is the diameter of a human hair than the diameter of a spider's silk?

Okay!

Here we go!

We do subtraction

9*10^(-5)-3*10^(-6)

This is 87/1000000

If the question is "how much greater" we have subtraction

9* 10^(-5) - 3* (10)^(-6) = 0.000087 m

If the question is "how many times greater" we have division

9 * 10^(-5) 3 * 10^6 3 * 10 = 30 times

_________ = _______ =

3 * 10^(-6) 10^5
