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