(-18) / 2/3

OpenStudy (anonymous):

\[\frac{-18}{\frac{2}{3}}\] Since you can always multiply the top and bottom by the same thing, I'd start by multiplying the outer fraction by 3/3 to clear the complex fraction.

OpenStudy (anonymous):

What would you get if you multiply by 3/3

OpenStudy (anonymous):

1?

OpenStudy (amistre64):

-9(3) is what I get...

OpenStudy (anonymous):

Yes, 3/3 is 1, but we want to write it as 3/3.

OpenStudy (amistre64):

i always turn the bottom fraction over, spank it, and slap it back down and multiply across....bad fraction...bad!!

OpenStudy (anonymous):

\[\frac{-18}{\frac{2}{3}} * \frac{3}{3} = \frac{(-18)(3)}{2}\]

OpenStudy (amistre64):

\[-18 * \frac{3}{2}\]

OpenStudy (amistre64):

OpenStudy (amistre64):

OpenStudy (anonymous):
