Okay, this is the last one I'm helping with. The same rule applies from the last problem.
Convert the division to multiplication by reciprocating the second fraction.
Confused
Hang on a minute
\(\begin{align*} \dfrac{9x - 18}{4} \div \dfrac{36}{8x - 24}\\\\ \dfrac{9x - 18}{4} \cdot \dfrac{8x - 24}{36}\\\\ \dfrac{9x - 18}{4} \cdot \dfrac{8(x - 3)}{36}\\\\ \end{align*}\)
Something seems to be off with the answer choices
One second. Let me try something else
Hmm okay
Okay, basically, they want us to factor it completely
@Nicole
Shout out to @photonics
factor out what
the numerators and denominators?
Where have you been?
Yes, factor everything completely. Let me know what you get
Lol, sorry I got busy with something other than school
9x-18: 9(x−2)
8x-24: 8(x−3) the rest are whole numbers so you cant factor
It can be factored further than that
Keep in mind \(36 = 9 \times 4\) and 2 is common to both 4 and 8
Oh I didnt know you can factor whole numbers
so 4 = 2*2
Yes, whole numbers are factorable if they are composite.
Okay so what is the next step

is it A?
Correct
