The first step is to change each of the decimals to a form that is easier to divide. Since I know how to divide 27/3 that is the form I will change to. 0.000027 needs to change to 27. Since the decimal moves to the right 6 places (or needs to be multiplied by 1,000,000) It can be written as 27x10^(-6). Now to change 0.000009 to 9. This follows the same steps as before to become 9x10^(-6). The new equation is (27x10^-6)/(9x10^-6) We know that 27/9 is 3. 10^-6/10^-6 is equal to 1 so the final answer is 3 x 1 = 3.
