what is 0.000027 divided by 0.000009

Question

please explain

Answer 1

Kayla,

 

First we can use exponential notation to rewrite 0.000027 as 27x10^-6 and 0.000009 as 9x10^-6.

 

Now divide:  (27x10^-6)/(9x10^-6).  The factors 10^-6 in the numerator and denominator cancel, so we are left with:

 

(27)/(9) = 3

Answer 2

multiply both numbers by 10⁶ which moves the decimal point to right six places.

 

you get 27 divided by 9 = 3
