- 5/9 x 6/8 =

OpenStudy (anonymous):

\[\frac{ -5*6 }{ 9*8 }\] Multiply this, what do u get?

OpenStudy (anonymous):

-30/72????

OpenStudy (anonymous):

is that the answer?

OpenStudy (anonymous):

Nope you need to simplify. Write the fraction in a simplier form.

OpenStudy (anonymous):

eg. 2/6 = 1/3 in its simpliest form.

OpenStudy (anonymous):

okay, give me a sec. :)

OpenStudy (anonymous):

-3/7?

OpenStudy (anonymous):

nope that's not it. you should have gotten -5/12

OpenStudy (anonymous):

huh? how did you get that, if you don't mind me asking?

OpenStudy (anonymous):

:/

OpenStudy (anonymous):

The greatest common factor between 30 and 72 is 6. So I divided both the numerator and the denominator by 6. That's how I got -5/12

OpenStudy (anonymous):

oh, thanks! I need to catch up on my GFC. Thanks soo much for your help! ;D

OpenStudy (anonymous):

Sure glad i could be of assistance!

OpenStudy (anonymous):

Actually, one more thing! Is the 12 also a negative?

OpenStudy (anonymous):

the entire fraction i negative: \[-\frac{ 5 }{ 12 }\]

OpenStudy (anonymous):

thanks again! :D
