# How to isolate algebraic fraction in this case i have a question about of how to isolate an equation, when it has a multiplication in the denominator. a/b/3 is same than a*(3/b) but, when is: a/(b/3 * 4/a) If i want to isolate the 4/a that is multiplying the b/3 and in turn dividing to a, so how isolate only the 4/a ?

How to isolate algebraic fraction in this case
i have a question about of how to isolate an equation, when it has a multiplication in the denominator.
a/b/3 is same than a*(3/b)
but, when is:
a/(b/3 * 4/a)
If i want to isolate the 4/a that is multiplying the b/3 and in turn dividing to a, so how isolate only the 4/a ?

we have
$\frac{a}{\frac{b}{3}\cdot \frac{4}{a}}=\frac{3{a}^{2}}{4b}$
