you need a lesson on exponents ...
Exponents: Basic Rules
go through all 5 pages thoroughly.
Or simply that $\displaystyle
\frac{2a^2 b}{ab^3} = \frac{2 \cdot a \cdot a \cdot b}{a \cdot b \cdot b \cdot b} = 2\left(\frac{a}{a}\right)\left(a\right)\left(\frac {b}{b}\right)\left(\frac{1}{b^2}\right)$
And $\displaystyle \frac{a}{a}= \frac{b}{b}= 1$.
