What is the quotient? n+3/2n-6 divided by n+3/3n-9

Stolb23 [73]

First some rewriting:

$\dfrac{n+3}{2n-6}\div\dfrac{n+3}{3n-9}=\dfrac{n+3}{2(n-3)}\div\dfrac{n+3}{3(n-3)}=\dfrac{\frac{n+3}{2(n-3)}}{\frac{n+3}{3(n-3)}}$

We see that the numerators of both fractions $(n+3)$ and a term in the denominators $(n-3)$ will cancel:

$\dfrac{n+3}{2(n-3)}\div\dfrac{n+3}{3(n-3)}=\dfrac{\frac12}{\frac13}$

Then

$\dfrac{\frac12}{\frac13}=\dfrac12\cdot\dfrac31=\dfrac32$
