It's the same thing principle: \[\frac{ -6 }{ 11 }*\frac{ 3 }{ 4 }=\frac{ -6*3 }{ 11*4 }=\frac{ ? }{ ? }\]
OpenStudy (anonymous):
-18 and 44
OpenStudy (anonymous):
you might want to check the solutions that your wrote though, or the question, cause the correct answer to the question you wrote isn't there
OpenStudy (anonymous):
but yes that is right. So what divides both -18 and 44?
OpenStudy (anonymous):
i don't know

okay, whatever divides 18, also divides -18
so what divides 18 and 44 (hint they are both even numbers)
OpenStudy (anonymous):
good you've edited the answers :)
OpenStudy (anonymous):
6
OpenStudy (anonymous):
not quite, 6 doesn't divide into 44. (it divides into 42 and 48 but not 44)
OpenStudy (anonymous):
11

nope, because 11 doesn't divide into 18.
(hint it's quite a small number this time)
OpenStudy (anonymous):
2
OpenStudy (anonymous):
yes! so if you have: \[\frac{ -18\div2 }{ 44\div2 }=\frac{ ? }{ ? }\] what do you get?
OpenStudy (anonymous):
9 and 22
OpenStudy (anonymous):
exactly. though the 9 will be negative (as it was -18)
