If it doesn't, then you'll know there's something wrong. The first thing to do is find the highest common factor (H.C.F) of \(10\) and \(4x\). This will tell us the term that will go outside the ...

frac{{{a^2}b}}{{a{b^2}}} = \frac{{a \times a \times b}}{{a \times b \times b}}\) Since a and b are both factors, cancel this fraction by dividing by both a and b from the top and bottom.
